Transient voltage overshoot is a common phenomenon in wide bandgap (WBG) power semiconductors due to high frequency and fast switching applications. An application driven repetitive transient off-state overvoltage datasheet specification is desired for design engineers. In this work, a 1% duty-cycle-based overvoltage specification is proposed by estimating the total lifetime … [Read more...] about Proposing a Duty Cycle Based Repetitive Drain Overvoltage Specification for GaN HEMTs

Alternative Way to Develop Small-Signal Models of Power Converters
The small-signal model of a switch-mode power converter is a useful tool in understanding its dynamic behavior and designing a proper compensator. In the power electronics community, people derive small-signal models almost always by perturbation and then extracting the small ac components manually from the whole system equations. This process is not systematic and potentially … [Read more...] about Alternative Way to Develop Small-Signal Models of Power Converters
Women in Engineering– Developing a Leadership Career Path at ECCE 2023
The Power Electronics Society’s five-year strategic plan includes enhancing career support and development programs. This focus on career development was clearly seen at IEEE Energy Conversion Congress & Expo (ECCE) 2023 with its Women in Engineering (WIE) events program covering aspects from early career to senior leadership. For more about this article see link … [Read more...] about Women in Engineering– Developing a Leadership Career Path at ECCE 2023
Industry Pulse– Report from Beijing
As a power electronics professional, but also a consumer, you are likely seeing frequent news stories about electric vehicles (EVs), and perhaps have driven or even own an electric car. In 2021, I purchased my first EV. But, it wasn’t a Tesla—300,000 cars sold in the U.S. in 2021 and 4 million sold globally that same year. It was a two-wheeled electric scooter, a mint-green … [Read more...] about Industry Pulse– Report from Beijing
Students and Young Professionals Rendezvous– The 2023 Year-End Report and 2024 Preview
In the last calendar year, there were many changes within the organization, and it included a challenge to increase the purview of the Students and Young Professionals (S&YP) committee, as well as the events and services that the committee organizes and supports. This was done in part as nearly all major events returned to in-person attendance. To start, the S&YP committee … [Read more...] about Students and Young Professionals Rendezvous– The 2023 Year-End Report and 2024 Preview
