Artificial General Intelligence (AGI) represents the ultimate frontier in the world of artificial intelligence—a vision of machines that think, learn, and understand as flexibly and broadly as humans do. Unlike today’s narrow AI systems that excel in specific tasks, such as translating languages or diagnosing diseases, AGI aims to bridge the gap between computational efficiency and human-like cognition. It’s the dream of creating an AI so versatile that it can seamlessly adapt to any intellectual challenge across diverse domains.

What Exactly is AGI?

AGI isn’t just about making machines smarter in specific ways; it’s about giving them a brainpower equivalent to our own. Imagine an AI that not only plays chess like a grandmaster but also writes poetry, learns to cook, solves intricate physics problems, and holds deep, meaningful conversations—all without needing to be reprogrammed for each task. AGI aspires to be this all-encompassing, adaptable system that can reason, learn, and apply knowledge to new situations, much like a human.

The Difference Between AGI and Narrow AI

To understand AGI, it’s essential to contrast it with what we currently have: “Narrow AI”.

Narrow AI dominates our lives today, powering virtual assistants like Alexa, recommendation algorithms on Netflix, and even self-driving cars. These systems are exceptionally good at what they’re designed to do but lack the ability to generalize or step outside their predefined capabilities. A narrow AI trained to diagnose diseases, for example, can’t suddenly start solving math equations.

AGI, in contrast, has the potential to overcome these constraints. It wouldn’t just perform tasks; it would learn how to approach them, adapt to new ones, and even innovate solutions we humans might never conceive.

The Path to AGI: Still a Theoretical Dream

At present, AGI remains a theoretical concept, with scientists and engineers dedicating their efforts to unraveling the complexities of human-like cognition. Progress is being made in areas like neural networks, reinforcement learning, and natural language processing, but creating a machine that truly “understands” remains elusive.

The challenge isn’t just computational—it’s deeply philosophical. How do we model consciousness, creativity, and abstract thinking? How do we design a machine capable of ethical reasoning or emotional intelligence? AGI isn’t just about programming; it’s about unraveling the mysteries of human thought itself.

The Promise and Peril of AGI

If achieved, AGI could revolutionize every facet of society. It could accelerate scientific discovery, solve complex global challenges like climate change, and redefine education and healthcare. Imagine a world where machines collaborate with humans to unlock limitless potential.

However, this vision isn’t without risks. AGI raises profound ethical questions: How do we ensure it aligns with human values? How do we prevent misuse? And how do we safeguard against scenarios where AGI outpaces our control? These are questions that must be addressed alongside technological progress.

The Road Ahead

AGI represents the culmination of human ambition—a synthesis of technology and intellect that mirrors our own capabilities. While it may still be a distant goal, its pursuit inspires us to explore the very essence of intelligence, creativity, and ethics. The journey to AGI isn’t just about building machines; it’s about redefining what it means to be human in a world of infinite possibilities.

Learn about our collaboration with NASA and industry leaders in developing radiation-hardened, plastic packaging for space electronics, known as QML Class P, to power missions with size, weight and power in mind.

As curiosity and innovation drive space exploration forward, constraints for size, weight and power continue to tighten. To design for space, you have little to no room for error. And increasing space exploration activities by public and private entities, whether in Earth’s orbit or way beyond, requires continued collaboration and improvements.

Recently, our company worked with NASA and other industry experts to lead the development of a new plastic packaging standard for space electronics, known as Qualified Manufacturers List Class P (QML Class P). Electronics in space must meet government standards set forth in the QML, ranging from radiation-tolerant or radiation-hardened devices in either ceramic or plastic packaging. The QML provides assurance that parts will operate as intended in the harsh environments of space.

“The QML Class P packaging standard enables more advanced computing in space, such as how satellites and other spacecraft can autonomously process data and make decisions in orbit as opposed to beaming data back down to Earth,” said Javier Valle, product line manager for space power at our company. “More processing capability also requires greater power. With TI’s QML Class P portfolio, we increase the efficiency of the power supply while reducing the size of the overall package, resulting in much higher power density.”

The QML exists with its many classes to ensure predictability in designs, meeting qualification and certification according to government standards, but new standards such as Class P are introduced as our knowledge and use cases advance. The QML Class P standard enables the use of radiation-hardened plastic packaging for power-management, processor, communications and high-speed integrated circuits (ICs) in satellites, rovers and other spacecraft.

Bring space up to speed through plastic

Ceramic packaging has often been the go-to, reliable option, as it meets a variety of government agency specifications in the United States. Manufacturers of ceramic-packaged space electronics have released ICs to the market under a qualification known as QML Class V.

Until QML Class P, there had been no standardized, radiation-hardened equivalent for plastic packaging.

Earlier forms of plastic packaging standards have also been especially vulnerable to a process known as outgassing. Outgassing describes a process when the harsh temperature and vacuum conditions of space vaporize organic compounds, which can deposit onto electronics causing them to fail. Depending on the severity, the effects of outgassing can interrupt or completely end missions.

Advancements in manufacturing and testing procedures have helped address the consequences of outgassing and other environmental concerns in space. However, these improvements can vary from manufacturer to manufacturer, and consequentially, were not enough to reassure space operators about the reliability of new, unfamiliar technologies without standardization.

In repeatedly hearing from customers that the industry needed a QML standard for plastic packaging, our company assembled a group of more than three dozen experts from industry and standardization bodies.

Looking further ahead with TI

Space operators can now easily transition from a radiation-tolerant electronic design using our Space Enhanced Plastic portfolio to a radiation-hardened design with our QML Class P portfolio, without any hardware change given our pin-to-pin compatibility.

TI’s QML Class P certified portfolio offers solutions across the entire spacecraft electrical power system (EPS), from solar panels all the way to point of load power supplies, and the portfolio is growing.

As we continue to navigate the future of space exploration, designing for space brings unlimited possibilities and solutions as endless as space itself. We have more than six decades of experience in creating solutions for space, and we look forward to helping you engineer the next frontier.

ELE Times: Quality and safety are always critical when it comes to components. How does Uchi ensure these aspects in its products?

Mr. Babu Ayyappan: As a distributor, our primary responsibility is to bring quality products to India. We carefully select companies based on their market reputation and business practices. Today, with globalization, anyone can purchase products from anywhere. However, the same product—say, a branded product from Espressif—can be sourced from multiple suppliers. At Uchi, we work directly with authorized distributors. We don’t go through third-party mediators to save costs or speed up imports because we can’t vouch for their practices. By maintaining direct relationships with trusted suppliers, we ensure we import only quality products. That’s the extent of control we have as a distributor in a vast global market.

ELE Times: How has your experience at this year’s event been? Did it meet your expectations, and what are your future plans?

Mr. Babu Ayyappan: Exhibitions serve multiple purposes for us. They allow us to meet customers we might not otherwise encounter, reconnect with existing ones, and engage new prospects.

Semiconductor innovations in battery systems are leading to energy storage adoption

Takeaways

• Power grids weren’t designed to handle new types of electricity demands and supplies.
• Battery energy storage systems are key to transforming and protecting the grid.
• Innovation in battery-management and high-voltage semiconductors help grids get the most out of battery storage.

The growing adoption of electric vehicles (EVs) and the transition to more renewable energy sources are reducing our more-than-century-long reliance on fossil fuels. Electric utilities are increasingly turning to solar panels and wind turbines rather than natural gas-fueled turbines to generate the electricity needed to charge EVs, as well as help power our homes and businesses. Together, these trends are poised to bring us closer to a sustainable energy future.

Those same trends also pose a big challenge to the electricity grid. Demand can vary throughout the day – and so can supplies of solar and wind energy based on changes in the weather. That’s why batteries are becoming an essential component of the grid.

“Batteries can fill in the gap when it’s cloudy and the wind dies down,” said Richard Zhang, a Virginia Tech professor who teaches power electronics and has worked in the grid and energy industry for 25 years. “And batteries improve the economics of electricity because they can be charged during off-peak times, providing electricity for charging EVs at peak times.”

Getting batteries to safely, reliably and cost-effectively store and release the large amounts of electricity running through the grid is a complex challenge. That’s where our company’s expertise in providing advanced battery-management semiconductor solutions can make a big difference.

“The bigger, higher-voltage batteries used in the grid require better thermal management and more precise monitoring,” said Samuel Wong, our company’s vice president and general manager of Battery Management Solutions. “Effectively managing those batteries requires understanding battery chemistry and adapting high-performance semiconductor devices to safely get the most out of each battery.”

Smoothing out the grid

The adoption of solar and wind generation and EVs is good news for the planet, Richard said. The problem is that power grids weren’t originally designed to handle these new types of electricity demands on available energy.

“Getting people to switch to EVs is easier today than it was just a few years ago,” he said. “Now the growing issue is getting the electricity infrastructure to handle them, alongside other energy demands.”

The challenge, Samuel said, is grid instability – in other words, fluctuations in electricity generation and usage. Variations in energy supply occur in solar and wind generation, especially the complete loss of solar power at night. Supply and demand swings may also occur from the charging routines of EV owners.

“If everyone comes home in the evening and plugs in their EVs for the night, the grid might not be able to handle it,” he said.

Samuel and Richard, like most power experts, agree on the solution to grid instability: energy storage systems (ESS). Storage systems – usually in the form of batteries – can capture and hold excess energy in the grid when supply is high and demand is low, and then make it available at other times. You may be picturing the relatively small, light battery cells used in EVs. But for the grid, an ESS might consist of a railroad-car-sized stack of bigger, heavier cells that each can operate at as much as 4 megawatt-hours (MWh) – enough energy to power thousands of homes.

Staging storage systems at different points in the grid optimizes their ability to distribute enormous amounts of electricity to neighborhoods when and where they’re needed. That can mean placing an ESS alongside a solar panel farm, where it can soak up the excess energy during the day and then pump it back out to the grid at night. Or, an ESS placed in a community can more easily grab energy from local rooftop solar panels and later supply the extra electricity needed to charge nearby EVs. “An ESS can serve as a local reservoir for the community,” Samuel said.

Managing battery and system performance

At the heart of storage systems are high-voltage battery modules – typically lithium-iron phosphate cells – capable of generating enormous amounts of heat if charged or discharged too quickly. These modules can also have shortened lifetimes if completely depleted too often.

Monitoring temperature and charge in these batteries requires extremely precise semiconductors, such as the BQ79616 industrial battery monitor, Samuel said. That’s because even tiny fluctuations in temperature and voltage can signal that a battery may need attention.

“You have to get to millivolt accuracy to know how much charge is left in a battery,” he said.

Our company’s extensive experience in ultra-precise battery monitors is proving essential in helping the ESS industry produce systems that can supply the grid with vital battery-management data. The results can have a big impact on the cost-effectiveness of a grid ESS, Samuel said.

“If you can only measure the charge in a 10-MWh ESS with 5% accuracy, then you can’t safely use more than 9.5 MWh,” he said. “Our battery monitors can get the accuracy measurement to 1%, which enables you to use 9.9 MWh.”

In addition to accurate battery monitoring, grid-scale energy storage systems such as the ones integrated with solar panel farms require efficient high-voltage power conversion that help reduce power losses when transferring power to and from the grid. These systems also rely on sensing and isolation technologies that help maintain system safety and stability, which is critical for managing electricity flow as high as 1500 V.

Impacting the future

For the foreseeable future, innovation in battery ESS looks to be the key to transform and protect the grid from the variabilities coming from solar and wind energy, as well as EV charging.

“It’s really exciting to contribute to strengthening the grid with innovations in energy storage,” Samuel said. “We can already do a lot today, and we’ll be able to do a lot more as we build out tomorrow’s smart grid.”

4. Prepaid Energy Meters: These meters are commonly used in locations where consumers wish to pay for energy before using it. The consumer credits the meter with a certain amount of energy, and once the credit is used up, the supply is disconnected. Prepaid meters are widely used in residential areas and allow for better control over energy costs.
5. Three-Phase Energy Meters: These meters are used for measuring energy consumption in three-phase electrical systems, which are commonly found in industrial and commercial applications. Three-phase energy meters are more intricate and designed to manage larger electrical loads. They provide accurate measurements of energy consumption in systems with multiple phases.

Working Principle of Energy Meter

 

The working principle of an energy meter involves the conversion of electrical energy into mechanical energy or directly into a digital signal. The operating principle differs based on the type of meter used. Here is a basic explanation of the working principles for electromechanical and electronic energy meters:

1. Electromechanical Energy Meter:
   • Electromagnetic Induction: The core working principle of electromechanical meters is electromagnetic induction. When current flows through a conductor placed in a magnetic field, it experiences a force that makes it move. In an energy meter, the current-carrying coil is placed in the magnetic field created by a permanent magnet or another coil, causing a rotating disc.
   • Rotation of Disc: The speed at which the disc rotates is proportional to the power consumed. This rotation is mechanically linked to the dials or counters that indicate the energy usage.
   • Friction Brake: A brake mechanism is applied to the disc to limit its speed, ensuring that it does not rotate too quickly, and the readings remain accurate.
2. Electronic Energy Meter:
   • Voltage and Current Sensing: Electronic meters use voltage and current sensors to continuously measure the electrical parameters of the system.
   • Digital Conversion: The measured analog signals (voltage and current) are fed into an analog-to-digital converter (ADC) that transforms the continuous signals into discrete digital signals.
   • Microcontroller Processing: A microcontroller processes the digital signals, calculating the energy consumed in real-time. The calculated data is shown on a digital display and saved for later reference.

Construction of an Energy Meter

The construction of an energy meter can vary depending on the type (electromechanical, electronic, or smart). However, the general components include the following:

1. Current Coil: This coil is placed in series with the load and carries the current to be measured. It generates a magnetic field that interacts with the magnetic field of the voltage coil, producing a mechanical torque in the case of electromechanical meters.
2. Voltage Coil: The voltage coil produces a magnetic field that interacts with the one created by the current coil. The voltage coil generates a magnetic field that interacts with the magnetic field produced by the current coil.
3. Rotating Disc (for electromechanical meters): The current and voltage coils generate a magnetic field that induces a torque on a metal disc. The disc rotates, and the speed of rotation is proportional to the power consumption. The mechanical motion of the disc drives the dials to display the energy used.
4. Digital Display (for electronic meters): Instead of mechanical dials, electronic energy meters have a digital display that shows the energy consumption in numerical form. A microcontroller processes the data to update the display in real-time.
5. Mechanical Dials: In older electromechanical meters, the disc’s motion is linked to a set of dials or gears that indicate the energy usage.
6. Brake Mechanism: A friction brake mechanism is applied to slow down the rotation of the disc in electromechanical meters, ensuring the meter measures the energy consumption accurately.
7. Transformer (optional): In some energy meters, especially for higher voltage systems, transformers are used to step down the voltage to safe, measurable levels.

Energy Meter Phasor Diagram

The phasor diagram is a graphical representation of the relationship between the voltage and current waveforms in an AC circuit. For energy meters, phasor diagrams help in understanding how the current and voltage are related, which is essential for accurate energy measurement.

In a typical AC circuit, the voltage and current waveforms are sinusoidal but may be out of phase. The angle between the voltage and current phasors indicates the phase difference. For active power (real power), the voltage and current are in phase, and the power factor is unity (1). However, in most practical cases, the current and voltage are not perfectly in phase due to inductive or capacitive components, leading to a power factor less than 1.

The energy meter measures the product of voltage and current over time, which is then displayed as the energy consumption. The phase difference between the current and voltage is critical, as it influences the calculation of the true power (active power) that the energy meter records.

Conclusion

Energy meters are indispensable tools in modern electrical systems, providing accurate measurement and monitoring of electrical energy usage. Whether electromechanical, electronic, or smart meters, they all serve the primary function of measuring electrical consumption. Understanding the construction, working principles, and types of energy meters helps consumers and utilities optimize energy management and ensure efficient billing practices. Phasor diagrams are a useful tool in understanding the relationship between voltage and current, aiding in accurate energy measurement, particularly in AC circuits.
