APEC 2024, Day 3: Daily Briefing Video

EDN Network - Thu, 02/29/2024 - 18:45

EDN editor-in-chief Majeed Ahmad and Power Electronics News editor-in-chief Maurizio Di Paolo Emilio discuss the highlights on day 3 of APEC 2024. One major topic included the move to a greener infrastructure for automotive manufacturing and more efficient automotive subsystems such as power trains. Wide bandgap (WBG) semiconductors such as SiC and GaN will be critical in realizing higher efficiencies for these systems moving forward. 

Majeed touched upon the rising popularity of GaN devices for applications outside its previous space of consumer electronics (e.g., USB chargers, AC adapters, etc.) and high frequency (RF) devices to other use cases such as data center power supplies and EV systems. Many players have, in recent years, made the claim that GaN can go beyond 650 V however, the jury is still out on its viability especially in large volumes. GaN power devices must contend with finding a suitable substrate to enhance factors such as power density, voltage capabilities, thermal performance, larger wafer sizes, long-term reliability, etc. Substrates for GaN vary from GaN-on-Si, GaN-on-SiC, to more specialty GaN-on-GaN, GaN-on-sapphire, and GaN on ceramics such as QST as accomplished by Vanguard International Semiconductor (VIS) in Taiwan. 

SiC technology has been steadily maturing where cost and wafer availability issues are appearing to ease up. Many exhibitors displayed wafers up to 8″and test and measurement (T&M) systems for wafer testing. Innovations in simulation tools such as QSPICE continue to keep up the pace with advances in SiC technologies, offering engineers a free platform rapidly to evaluate designs. Finally, Maurizio covers the non-WBG technologies revealed including a hydrogen fuel cell power system by Kohler Energy.

Photosensitivity: Seizures from displays

EDN Network - Thu, 02/29/2024 - 17:53

A couple of years ago, I described having witnessed someone undergo an epileptic seizure at the company where I was employed at the time. I tried to keep cool and collected while writing about that incident, but the truth be told, it was jarring. Please read the story here.

I was idly browsing on my “smart” phone the other day when I came across an item about a then upcoming Star Wars movie where clever computer people had recreated the character Princess Leia as she would have been portrayed by the late Carrie Fisher. I was taken aback by an admonishing note on the link, but I grasped its justification as I watched the clip itself (Figure 1).

Figure 1 Film clip of the upcoming Star Wars movie with the warning “Contains flashing images”

Before one gets to watch the clip showing off the video technology that has been brought to bear, there is a warning about “flashing images”. When the film clip runs, the rapid flash-flash-flash for which Star Wars films are noted actually had a somewhat disorienting effect on yours truly and I do NOT have any epileptic history.

The point of all this is that those of us whose work products involve display(s) of any kind need to be cognizant of the possible dangers that a flashing display might present to some users of the product(s).

Some of us will recall that this was one of the plot devices in the movie The Andromeda Strain back in 1969 in which a woman is driven by a flashing image into an epileptic attack.

From more than half a century ago right up to this very moment, this concern is for real and quite frankly, I am glad to see it having been addressed as shown in Figure 1.

Infineon introduces new Solid-State Isolators to deliver faster switching with up to 70 percent lower power dissipation

ELE Times - Thu, 02/29/2024 - 12:38

At the Applied Power Electronics Conference (APEC), Infineon Technologies introduced a new product family of Solid-State Isolators to achieve faster and more reliable circuit switching with protection features not available in optical-based solid-state relays (SSR). The isolators use coreless transformer technology and support 20 times greater energy transfer with both current and temperature protection contributing to a higher reliability and lower cost of ownership. The new solid-state isolators allow driving the gates of Infineon’s MOS-controlled power transistors OptiMOS and CoolMOS to reduce power dissipation of up to 70 per cent of today’s solid-state relays using SCR (silicon-controlled rectifier) and Triac switches.

Infineon’s solid-state isolators enable custom solid-state relays capable of controlling loads
more than 1000 V and 100 A. Improved performance and reliability make coreless transformer technology ideal for applications in advanced battery management, energy
storage, renewable energy systems, as well as industrial and building automation system
applications. With Infineon’s solid-state isolator drivers, engineers can further improve the
efficiency of electronic and electromechanical systems.

“Implementing coreless transformers in solid-state isolators and relays is truly a game
changer for power engineers; it provides 50 times lower RDS(on) than existing optically
controlled solutions. This enables their use in higher-voltage and higher-power
applications,” said Davide Giacomini, Marketing Director for the Green Industrial Power
Division at Infineon Technologies.

When matched with Infineon’s CoolMOS S7 switch, the isolator drivers enable switching
designs with a much lower resistance compared to optically driven solid-state solutions.
This translates to longer lifespans and lower cost of ownership in system designs. As with
all-solid-state isolators, the devices also offer superior performance compared to electromagnetic relays, including 40 per cent lower turn-on power and increased reliability
due to the elimination of moving parts.

The family of devices is designed to be compatible with Infineon’s broad switching portfolio
including Infineon’s CoolMOS S7, OptiMOSTM and linear FET portfolios.

How Human Intelligence and Video Analytics Level up Security

ELE Times - Thu, 02/29/2024 - 10:51

Author: Anuj Rajain, CEO at Soteria

When you think of “security,” what comes to mind? Cameras? Bodyguards? Surveillance systems? In ensuring security, the initial requirement is surveillance systems. A fundamental surveillance system records videos and audio from a specific location. To enhance the proactive and effective nature of this security system, human intelligence is essential. Human intelligence is a central factor that accelerates the process of monitoring and detecting crimes. Human intelligence and video analytics complement each other, reaching their full potential only through their coexistence.

Anuj Rajain, CEO at Soteria

Consider a scenario where surveillance systems operate without the incorporation of human intelligence, a system designed solely to monitor a location, lacking the human element to determine whether a situation involves detecting a criminal act or not. Video analytics currently lacks the sophistication to discern whether an act captured on video is criminal, suspicious, or benign. Consider a home surveillance system, particularly one in the garage. The video analytics in place struggles to differentiate between a person simply walking by and someone with criminal intent, such as attempting to steal a car. Relying solely on AI in such situations may result in numerous false alarms, raising concerns about the trustworthiness and reliability of surveillance systems. To address this issue, an understanding of human emotions and the ability to differentiate between various actions are crucial. This emphasizes the necessity of incorporating human insight to navigate the limitations of current video analytics and ensure the accurate interpretation of events.

If we focus solely on the reliance on human intelligence for maintaining and overseeing security, it becomes evident that this approach alone is not feasible. The absence of security cameras or a surveillance system would result in a chaotic environment, providing an opportunity for more criminal acts to be committed. Human intelligence, while essential, cannot cover all angles and monitor every inch of space continuously. Security cameras and surveillance systems play a crucial role in providing a comprehensive and continuous watchful eye over a location. They act as force multipliers, extending the reach of human intelligence and enhancing the overall effectiveness of security measures. Without these technological tools, security efforts would face significant limitations, making it challenging to prevent and respond to criminal activities in a timely and efficient manner. Therefore, the integration of both human intelligence and advanced surveillance technologies is essential for creating a robust and comprehensive security infrastructure.

The landscape of security camera technology is continuously advancing, becoming not only more efficient but also more effective and cost-effective. The integration of innovative security technologies, coupled with human intelligence, introduces multiple layers of security for enhanced protection. Businesses that invest in surveillance cameras featuring remote monitoring capabilities stand to reap significant benefits. Beyond the traditional security aspect, such systems contribute to increased productivity and an enhanced customer experience. The constant evolution of security camera technology ensures that companies can stay ahead in safeguarding their assets, premises, and personnel. This investment not only strengthens security measures but also proves to be a strategic move, optimizing operational efficiency and positively impacting the overall profitability of the business.

To sum up, it’s crucial to have both human intelligence and advanced surveillance technology working together for strong security. Surveillance systems keep a constant watch, but human understanding is necessary for tricky situations. As security cameras get better, they become more efficient and cost-effective, giving businesses complete solutions. Using both these aspects not only protects assets but also makes operations smoother and improves customer experiences. In today’s changing security landscape, businesses need to integrate human intelligence and the latest surveillance tech to stay ahead and maintain a safe and successful environment.
