In the dynamic world of engineering design, the escalating requirements placed on power systems frequently give rise to intricate design challenges. The evolving landscape of DC power systems introduces complexities that can manifest stumbling blocks in the design process. Fundamental skills related to power supplies play a crucial role in mitigating these challenges.

Today’s advanced DC power systems are not immune to design problems, and a solid foundation in power supply knowledge can prove instrumental in navigating and overcoming hurdles. Whether it’s discerning the intricacies of device under test (DUT) voltage or current, addressing unforeseen temperature fluctuations, or managing noise sensitivity; a fundamental understanding of power supplies empowers designers to identify and tackle the nuanced issues embedded within a power system.

Understanding constant voltage and constant current

One of the most important concepts for anyone using power supplies is understanding constant voltage (CV) and constant current (CC). For engineers getting started with power supplies they must know some of the basic rules when it comes to CV and CC. The output of a power supply can operate in either CV or CC mode depending on the voltage setting, current limit setting, and load resistance.

In scenarios where the load current remains low and the drawn current falls below the preset current limit, the power supply seamlessly transitions into CV mode. This mode is characterized by the power supply regulating the output voltage to maintain a constant value. In essence, the voltage becomes the focal point of control, ensuring stability, while the current dynamically adjusts based on the load requirements. This operational behavior is particularly advantageous when dealing with varying loads, as it allows the power supply to cater to diverse current demands while steadfastly maintaining a consistent voltage output.

In instances where the load current surges to higher levels, surpassing the predefined current setting, the power supply shifts into CC mode. This response involves the power supply imposing a cap on the current, restricting it to the pre-set value. Consequently, the power supply functions as a guardian, preventing the load from drawing excessive current.

In CC mode, the primary focus of regulation shifts to the current, ensuring it remains consistent and in line with the predetermined setting. Meanwhile, the voltage dynamically adjusts in response to the load’s requirements. This operational behavior is particularly crucial in scenarios where the load’s demands fluctuate, as it ensures a stable and controlled current output, preventing potential damage to both the power supply and the connected components. Understanding this interplay between voltage and current dynamics is essential for engineers and users to harness the full potential of power supplies, especially in applications with varying load conditions.

Most power supplies are designed in such a way that it is optimized for CV operation. This means that the power supply will look at the voltage setting first and adjust all other secondary variables to achieve the programmed voltage. For a visual representation, see Figure 1 on the operating locus of a CC/CV power supply.

Boosting voltage or current

In instances where the demands of an application exceed the capabilities of a single power supply, a practical solution is to combine two or more power supplies strategically. This can be particularly useful when users need more voltage or current than a single power supply unit can deliver.

For scenarios demanding higher voltage, the method involves connecting the outputs of the power supplies in series. This arrangement effectively adds the individual voltage outputs, resulting in an aggregate voltage that meets the specified requirements. On the other hand, requiring a higher current, connecting the power supply outputs in parallel proves advantageous. This configuration combines the current outputs, providing a cumulative current output that satisfies the application’s demands.

To achieve optimal results, it is crucial to set each power supply output independently. This ensures that the voltages or currents align harmoniously, summing up to the total desired value. By following these simple yet effective steps, users can harness the collective power of multiple power supplies, tailoring their outputs to meet the specific voltage and current requirements of the application.

For higher voltage, first set each output to the maximum desired current limit the load can safely handle. Then, equally distribute the total desired voltage to each power supply output. For example, if engineers are using three outputs, set each to one third the total desired voltage:

1. Never exceed the floating voltage rating (output terminal isolation) of any of the outputs.
2. Never subject any of the power supply outputs to a reverse voltage.
3. Only connect outputs that have identical voltage and current ratings in series.

For higher current, equally distribute the total desired current limit to each power supply:

1. One output must operate in constant voltage (CV) mode and the other(s) in constant current (CC) mode.
2. The output load must draw enough current to keep the CC output(s) in CC mode.
3. Only connect outputs that have identical voltage and current ratings in parallel.

See Figure 2 for a visual representation of a series connection with remote sense to a load.

In the parallel setup, the CV output determines the voltage at the load and across the CC outputs (Figure 3). The CV unit will only supply enough current to fulfill the total load demand.

Dealing with unexpected temperature effects

Temperature fluctuations not only impact the behavior of DUTs but also exert a significant influence on the precision of measurement instruments. For example, during a chilly winter day, an examination of Lithium-ion batteries at room temperature yielded unexpected results. Contrary the user’s anticipation of a decrease, the voltage of the cells drifted upward over time.

This phenomenon was attributed to the nighttime drop in room temperature, which paradoxically led to an increase in cell voltage. This effect proved more pronounced than the anticipated decrease resulting from cell self-discharge during the day. It’s worth noting that the power supplies responsible for delivering power to these cells are also susceptible to temperature variations.

To accurately characterize the output voltage down to microvolts, it becomes imperative to account for temperature coefficients in the application of power. This adjustment ensures a more precise understanding of the voltage dynamics, accounting for the impact of temperature on both the DUTs and the measurement instruments.

The following is an example using a power supply precision module that features a low-voltage range. The test instrumentation specification table documents the valid temperature range at 23°C ±5°C after a 30-minute warm-up.

1. To apply a temperature coefficient, engineers must treat it like an error term. Let’s assume that the operating temperature is 33°C, or 10°C above the calibration temperature of 23°C and a voltage output of 5.0000 V.

Voltage programming temperature coefficient = ± (40 ppm + 70 μV) per °C

2. To correct for the 10°C temperature difference from calibration temperature, engineers will need to account for the difference in the operating temperature and voltage range specification. The low voltage range spec is valid at 23°C ±5°C or up to 28°C. Engineers will need to apply the temperature coefficient for the (5°C) difference in the operating temperature (33°C) and low voltage range spec (28°C):

± (40 ppm * 5 V + 70 μV) * 5°C = 40ppm * 5 V * 5 °C + 70 μV * 5 °C = 1.35 mV

3. The temperature-induced error must be added to the programming error for the low-voltage range provided in the N6761A specification table:

± (0.016 % * 5 V + 1.5 mV) = 2.3 mV

4. Therefore, the total error, programming plus temperature, will be:

± (1.35 mV + 2.3 mV) = ±3.65 mV

5. That means user output voltage will be somewhere between 4.99635 V and 5.00365 V when attempting to set the voltage to 5.0000 V in an ambient temperature of 33°C. Since the 1.35 mV part of this error is temperature-induced, as the temperature changes, this component of the error will change, and the output of the power supply will drift. The measurement drift with temperature can be calculated using the supply’s temperature coefficient.

Dealing with noise sensitive DUTs

If the DUT is sensitive to noise, engineers will want to do everything they can to minimize noise on the DC power input. The easiest thing users can do is use a low-noise power supply. But if one is not available, there are a couple of other things engineers can do.

The links between the power supply and the DUT are vulnerable to interference, particularly noise stemming from inductive or capacitive coupling. Numerous methods exist to mitigate this interference, but employing shielded two-wire cables for both load and sense connections stands out as the most effective solution. It is essential, however, to pay careful attention to the connection details.

For optimal noise reduction, connect the shield of these cables to earth ground at only one end, as illustrated in Figure 4.

Figure 4 To reduce noise connect the shield to earth ground only on one end of the cable. Source: Keysight

Avoid the temptation to ground the shield at both ends, as this practice can lead to the formation of ground loops, as depicted in Figure 5. These loops result from the disparity in potential between the supply ground and DUT ground.

Figure 5 Diagram where the shield is connected to ground at both ends resulting in a ground loop. Source: Keysight

The presence of a ground loop current can induce voltage on the cabling, manifesting as unwanted noise for your DUT. By adhering to the recommended practice of grounding the shield at a single end, you effectively minimize the risk of ground loops and ensure a cleaner, more interference-resistant connection between your power supply and the DUT.

Also, common-mode noise is generated when common-mode current flows from inside a power supply to earth ground and produces voltage on impedances to ground, including cable impedance. To minimize the effect of common-mode current, equalize the impedance to ground from the plus and minus output terminals on the power supply. Engineers should also equalize the impedance from the DUT plus and minus input terminals to ground. Use a common-mode choke in series with the output leads and a shunt capacitor from each lead to ground to accomplish this task.

Choosing the right power supply

Navigating the selection process for a power supply demands careful consideration of the specific requirements. Whether in need of a basic power supply or one with more advanced features tailored for specific applications, the ramifications of choosing a power supply with excessive power capacity can result in numerous challenges.

Common issues associated with opting for a power supply with too much power include increased output noise, difficulties in setting accurate current limits, and a compromise in meter accuracy. These challenges can be particularly daunting, but developing basic skills related to power supplies can significantly aid in overcoming these design obstacles.

By cultivating a foundational understanding of power supply principles, such as the nuances of CV and CC modes, engineers can effectively address issues related to noise, current limits, and meter accuracy. This underscores the importance of not only selecting an appropriate power supply but also ensuring that users possess the essential skills to troubleshoot and optimize the performance of the chosen power supply in their specific applications. Striking a balance between power capacity and application needs, while honing basic skills, is key to achieving a harmonious and effective power supply setup.

Intel joins hands with Taiwanese fab United Microelectronics Corp. (UMC) in a new twist in the continuously evolving and realigning semiconductor foundry business. What does Intel’s strategic collaboration with UMC mean, and what will these two companies gain from this tie-up? However, before we delve into the motives of this semiconductor manufacturing partnership, below are the basic details of this foundry deal.

Intel and UMC will jointly develop a 12-nm photolithography process for high-growth markets such as mobile, communication infrastructure and networking, and the production of chips at this 12-nm node will begin at Intel’s Fabs 12, 22, and 32 in Arizona in 2027. The 12-nm process node will be built on Intel’s FinFET transistor design, and the two companies will jointly share the investment.

Figure 1 UMC’s co-president Jason Wang calls this tie-up with Intel a step toward adding a Western footprint. Source: Intel

Besides fabrication technology, the two companies will jointly offer EDA tools, IP offerings, and process design kits (PDKs) to simplify the 12-nm deployment for chip vendors. It’s worth mentioning here that Intel’s three fabs in Arizona—already producing chips on 10-nm and 14-nm nodes—aim to leverage many of the tools for the planned 12-nm fabrication.

Intel claims that 90% of the tools have been transferable between 10-nm and 14-nm nodes; if Intel is able to employ these same tools in 12-nm chip fabrication, it will help reduce additional CapEx and maximize profits.

While the mutual gains these two companies will accomplish from this collaboration are somewhat apparent, it’s still important to understand how this partnership will benefit Intel and UMC, respectively. Let’s begin with Intel, which has been plotting to establish Intel Foundry Services (IFS) as a major manufacturing operation for fabless semiconductor companies.

What Intel wants

It’s important to note that in Intel’s chip manufacturing labyrinth, IFS has access to three process nodes. First, the Intel-16 node facilitates 16-nm chip manufacturing for cost-conscious chip vendors designing inexpensive low-power products. Second is Intel 3, which can produce cutting-edge nodes using extreme ultraviolet (EUV) lithography but sticks to tried-and-tested FinFET transistors.

Third, Intel 18A is the cutting-edge process node that focuses on performance and transistor density while employing gate-all-around (GAA) RibbonFET transistors and PowerVia backside power delivery technology. Beyond these three fab offerings, IFS needs to expand its portfolio to serve a variety of applications. On the other hand, its parent company, Intel, will have a lot of free capacity while it moves its in-house CPUs to advanced process nodes.

So, while Intel moves the production of its cutting-edge process nodes like 20A and 18A to other fabs, Fabs 12, 22, and 32 in Arizona will be free to produce chips on a variety of legacy and low-cost nodes. Fabs 12, 22, and 32 are currently producing chips on Intel’s 7-nm, 10-nm, 14-nm, and 22-nm nodes.

More importantly, IFS will get access to UMC’s large customer base and can utilize its manufacturing expertise in areas like RF and wireless at Intel’s depreciated and underutilized fabs. Here, it’s worth mentioning Intel’s similar arrangement with Tower Semiconductor; IFS will gain from Tower’s fab relationships and generate revenues while fabricating 65-nm chips for Tower at its fully depreciated Fab 11X.

IFS is competing head-to-head with established players such as TSMC and Samsung for cutting-edge smaller nodes. Now, such tie-ups with entrenched fab players like UMC and Tower enable IFS to cater to mature fabrication nodes, something Intel hasn’t done while building CPUs on the latest manufacturing processes. Moreover, fabricating chips at mature nodes will allow IFS to open a new front against GlobalFoundries.

UMC’s takeaway

UMC, which formed the pure-play fab duo to spearhead the fabless movement in the 1990s, steadily passed the cutting-edge process node baton to TSMC, eventually resorting to mature fabrication processes. It now boasts more than 400 semiconductor firms as its customers.

Figure 3 The partnership allows UMC to expand capacity and market reach without making heavy capital investments. Source: Intel

The strategic collaboration with IFS will allow the Hsinchu, Taiwan-based fab to enhance its existing relationships with fabless clients in the United States and better compete with TSMC in mature nodes. Beyond its Hsinchu neighbor TSMC, this hook-up with Intel will also enable UMC to better compete amid China’s rapid fab capacity buildup.

It’ll also give UMC access to 12-nm process technology without building a new manufacturing site and procuring advanced tools. However, UMC has vowed to install some of its specialized tools at Fabs 12, 22, and 32 in Arizona. The most advanced node that UMC currently has in its arsenal is 14 nm; by jointly developing a 12-nm node with Intel, UMC will expand its know-how on smaller chip fabrication processes. It’ll also open the door for the Taiwanese fab on smaller nodes below 12 nm in the future.

The new fab order

The semiconductor manufacturing business has continuously evolved since 1987 when a former TI executive, Morris Chang, founded the first pure-play foundry with major funding from Philips Electronics. UMC soon followed the fray, and soon, TSMC and UMC became synonymous with the fabless semiconductor model.

Then, Intel, producing its CPUs at the latest process nodes and quickly moving to new chip manufacturing technologies, decided to claim its share in the fab business when it launched IFS in 2021. The technology and business merits of IFS aside, one thing is clear. The fab business has been constantly realigning since then.

That’s partly because Intel is the largest IDM in the semiconductor world. However, strategic deals with Tower and UMC also turn it into an astute fab player. The arrangement with UMC is a case in point. It will allow Intel to better utilize its large chip fabrication capacity in the United States while creating a regionally diversified and resilient supply chain.

More importantly, Intel will be doing it without making heavy capital investments. The same is true for UMC, which will gain much-needed expertise in FinFET manufacturing technologies as well as strategic access to semiconductor clients in North America.

CleverTap, the all-in-one engagement platform today announced the top 2024 MarTech Trends which will transform the way brands deliver customer experiences.

The convergence of data privacy regulations, advancements in AI and increasing demand for personalized content will redefine the MarTech landscape. Among other areas, here’s where CleverTap anticipates seeing the most activity in 2024:

1. AI: the new-age consultants 

As customer engagement evolves, Generative AI will go beyond mere suggestions to definitive prescriptions. It will guide brands toward optimal courses of action, transforming customer engagement into not only a personalized but strategically optimized experience. In 2024, this development will manifest in two key areas: content prescription and customer engagement strategies. In content prescription, it will allow brands to analyze data, predict resonant content for specific customer cohorts, and generate new content. Prescriptive customer engagement strategies will enable proactive customer journey orchestration, granular user segmentation for hyper-personalization, and predictive analytics that anticipate needs and forecast long-term revenue impact.

2. From Return On Investment (ROI) to Return on Experiences (ROX)

While ROI has historically been the way to evaluate campaigns: “money in vs money out”, 2024 will see brands take a more holistic view that extends beyond immediate returns — return on experience (ROX). The approach will continually evaluate the long-term impact on customer experiences. It will be a more nuanced and precise metric for gauging customer success, helping marketers look at customer journeys historically and go beyond click-throughs and conversions. Instead, it will consider nuanced metrics such as brand perception, satisfaction, loyalty, and advocacy. The full spectrum of interactions and emotions is responsible for driving user engagement.

3. The gambit of omnichannel will expand 

Advancements in generative AI are coming thick and fast. And the chatbots spawned in 2023 will soon transition from being mere large language models to large action models. This means they will not just be able to respond with text, but also act upon commands, giving rise to an era of Generative AI assistants. The Rabbit R1 is already giving the world a pique into this by letting go of traditional apps in exchange for AI. The device’s software is powered by a large action model, or an algorithm that can learn from how users use apps so that it can replicate and automate those processes. In 2024, marketers will contend with the challenge of integrating these AI assistants into their omnichannel engagement strategies.

4. Zero-party data: consensual and accurate

The petabytes of data and insights brands have on their customers comes with a crucial responsibility i.e. ethically navigating this repository of information to deliver the best results while not compromising trust. Customers are increasingly wary of their data, how it’s being used and whether it’s being protected. 2024 will see the end of third-party cookies, the most popular targeting and tracking technique. As brands transition away, they will not only need to align with regulatory changes but also foster a transparent and trustworthy relationship with their audience. In this new era, the focus on ethical data practices will become a cornerstone of effective and responsible marketing strategies.

Jacob Joseph, VP – Data Science, CleverTap said, “2023 was the year of generative AI, whose profound impact on society had us both excited and cautious about what the future holds. While advancements in the field will make it a sustained talk-point in 2024, other developments will reach a tipping point too. By getting ahead of this curve, we at CleverTap, can not only adapt to these shifts but also innovate and leverage any advancements for the benefit of our customers. This approach ensures that our customers receive unparalleled value and stay at the forefront of the rapidly evolving tech landscape.”

The interim budget for the fiscal year 2024-25 is scheduled for February 1, 2024, as will be presented by Finance Minister Nirmala Sitharaman. The full and final budget is expected to be tabled in July, post-2024 Lok Sabha Elections. Between January 31 to February 9, a brief Budget session, the last of the 17th Lok Sabha will be held.

While many of us are expecting some indispensable leaps in several areas including technology, innovation, manufacturing, and R&D, FM Sitharaman while speaking at an event by the Confederation of Indian Industry (CII) ruled out the possibility of any “spectacular” announcements. This cements the fact that fiscal discipline will take precedence over populist spending, thus following the premise of a conventional interim budget model.

It will be interesting to see the stance that this budget will adopt, especially in expediting growth in the Power and Energy sector with lead incentivization for green hydrogen. The oil and gas sector has expectations of steady reforms for City Gas Distribution players, while the power sector is keen on noticing some bold initiatives to encourage the adoption of renewable energy. As per EY’s 2024 Budget expectations report, the government may extend the concessional 15 per cent income tax rate for corporations, for them to set up manufacturing units by one year till March 31, 2025, to attract foreign investments. Experts also predict that the government could unveil an expanded third phase of the incentive scheme for electric vehicles and that the budget will cater to further strengthening of the startup ecosystem in the country.

Overall, India is expected to maintain the growth momentum into FY25, and the upcoming union budget can indeed be a solid step towards realizing the country’s ambition of becoming the third-largest economy.

Let us take a look at what some of the industry experts’ expectations are from this year’s interim budget, as shared with ELE Times.

Shubham Vishvakarma, Co-Founder and Chief of Process Engineering at Metastable Materials

“As we anticipate the 2024 budget announcement, we hope for a forward-looking budget that reflects India’s commitment to sustainability and technology advancement. A large volume of India’s end-of-life Lithium-ion batteries is exported globally for recycling or just processed as an intermediate black mass and then exported. Hence, massive R&D investments are required, particularly to create strong competencies and lab testing facilities for the proper end-of-life Lithium-ion battery recycling. This not only contributes to responsible environmentalism but also nurtures a talented pool of individuals.

Another area, where we are hopeful for is the Production-Linked Incentive (PLI) and it’s extension to battery recycling. This would also be a strategic approach as by expanding the range of the scheme beyond just the Advanced Chemistry Cell manufacturing, we open up the opportunity to capture the entire value chain. This extension will incentivize the setting up of homegrown recycling firms instead of shipping away the dead batteries.

We also recommend that the recycling of Lithium-ion batteries be incorporated into the Carbon Credit Trading Scheme. This inclusion, in particular for negative-value battery chemistries feasibility will provide substantial support to India’s position in the carbon credit markets and also demonstrates our continued dedication to sustainable solutions.”

Manideep Katepalli, Co-Founder at BikeWo –

“Despite last year’s commendable 33% surge in EV registrations, our industry encounters persistent challenges. Chief among these hurdles is the imperative need for robust charging infrastructure, pivotal in inspiring confidence among potential buyers and propelling the widespread adoption of electric vehicles (EVs) as a sustainable mode of transportation.

Another barrier remains the relatively higher initial cost of EVs, often deterring consumers. However, the promise of life tax subsidies for electric vehicles and the availability of accessible EV financing options hold immense potential to mitigate this challenge.
The integration of EV infrastructure into Priority Sector Lending (PSL) is poised to bolster credit flow into the sector by mandating financial institutions to provide support, thus promising a significant boon. A supportive regulatory framework coupled with financial incentives aimed at fostering research and development within the EV sector stands as an indispensable pillar. These measures not only drive innovation but also attract investments, creating an environment conducive to widespread EV adoption. Ultimately, these strategic initiatives play a pivotal role in establishing an enduringly sustainable and eco-friendly transportation ecosystem”.

“Prioritizing the electric vehicle (EV) sector is crucial for a sustainable future. First, inclusion in the priority lending scheme will fuel growth by facilitating easier access to capital. To accelerate the adoption of EV-led delivery services, a reduction in GST for EV services from 18% to 5% is imperative. While EV purchases enjoy a 5% GST rate compared to 28% for internal combustion engine (ICE) vehicles, a similar distinction must extend to services. Furthermore, introducing usage-based incentives for EV drivers, in addition to existing FAME buyer incentives, will be a game-changer. Rewarding users based on carbon savings and kilometres driven creates a tangible incentive for sustainable choices.

Addressing the last-mile delivery gap is equally critical. Recognizing last-mile delivery as a distinct sector under logistics policies is essential, given that one-third of shipments fall within this category. Establishing industry standards, supporting gig delivery partners with tailored schemes, and implementing standard operating procedures (SOPs) will enhance efficiency and foster growth in this vital but often overlooked segment of the logistics industry”.

Dinesh Arjun, CEO & Co-Founder at Raptee-

“As the electric vehicle (EV) industry gears up for substantial growth in the coming years, it is imperative for the government to foster a supportive ecosystem. To stimulate investment opportunities, there should be encouragement for potential investors, coupled with essential reductions in GST rates for electric vehicles and charging stations. Additionally, easing the burden on the industry can be achieved through a decrease in import duties on electronic components. The industry is particularly hopeful for a significant GST reduction, aiming to bring it down from 18% to 5% specifically for lithium-ion battery packs and cells, given their pivotal role in the EV sector. A concerted effort in the budget towards enhancing the ease of doing business and facilitating the entry of local players into the market is crucial. Addressing aspects like component localization and ensuring easy access to necessary components will empower Indian companies, both large and small, to develop competitive products at competitive prices, further solidifying the sector’s growth potential”.

Ritesh Kumar, Founder at Cyfirma-

“We would like to see the upcoming budget carry a strong focus on helping businesses overcome the threats of cyberattacks and other digital risks. Indian businesses are adopting digital solutions at an accelerated pace yet their cybersecurity maturity remains low. A budget that supports SMEs and start-ups growth while ensuring their cybersecurity needs are taken care of is much needed in the current AI and digital age. The government’s approach needs to move beyond building compliance frameworks to providing tangible subsidies for cybersecurity protection solutions”.

Yogesh Mudras, Managing Director, Informa Markets in India

“The Budget 2024-25 becomes pivotal in steering the nation towards a greener future. With a commitment to boost green energy to 500 GW by 2030, we anticipate sustained attention on the increased allocations for bio-energy, solar, and wind, alongside higher capital expenditure in green hydrogen and battery storage infrastructure.

Recognizing the critical role of energy storage for grid stability, we applaud the proposed policy incentives for Battery Energy Storage Systems (BESS). The recent approval of a scheme targeting 4,000 MWh of BESS projects by 2030-31, with financial support of up to 40% (Rs. 3,760 crore), marks a significant stride toward a resilient energy landscape.

As India targets 170 GW Renewable Energy capacity by March 2025, the Budget is anticipated to extend existing schemes, including the Production Linked Incentive and viability gap funding. Advocating for policies that stimulate green hydrogen demand, reduce GST on crucial components, and increase funding for R&D to create a stable environment for sustainable development. Informa Markets by organizing The Battery Show and REI Expo, continues to provide a crucial platform for industry leaders to collaborate and contribute to the nation’s sustainable energy journey.”
