Due to the environmental concerns about CO2-caused global warming, policymakers are pushing electrified vehicles (EVs) to reduce these emissions. For passenger vehicles only, the electrified fleet is forecasted to reach 80 million in the U.S. and 500 million globally by 2040. Key enablers for such rapid EV adoption include the improvement of battery energy density, lifespan and … [Read more...] about Charging Electric Vehicle Batteries: Wired and Wireless Power Transfer

Practical Realization of GaN’s Capability
The system-level value of wide bandgap power semiconductors of higher efficiency, smaller size and weight, and more sustainable energy usage in our power supplies and motor drives is being demonstrated now. Gallium nitride (GaN) power FETs are replacing silicon (Si) power MOSFETs in applications from 48 V to 800 V. Silicon carbide (SiC) is replacing legacy IGBTs in applications … [Read more...] about Practical Realization of GaN’s Capability
Supercapacitor Assisted Surge Absorber Technique: high performance transient surge protectors for consumer electronics
Invention of the transistor in 1947 made a radical change to the path of the development of electronic products and systems. In the mid-1950s, integrated circuits (ICs) started evolving rapidly, creating miniaturized analog, digital and mixed signal circuits. By the 1960s to 1970s, microprocessors, memories and power semiconductors entered the electronic marketplace. During the … [Read more...] about Supercapacitor Assisted Surge Absorber Technique: high performance transient surge protectors for consumer electronics
Distinguished Plenary Speakers Chart Future Technology Path for APEC 2022
For the last two years, the IEEE Applied Power Electronics Conference and Exposition (APEC) was organized in a virtual format due to the COVID-19 pandemic. This year, the leading international conference was delivered in a hybrid format in Houston, Texas, 20–24 March at the George R. Brown Convention Center. Because some overseas and domestic participants in our community, … [Read more...] about Distinguished Plenary Speakers Chart Future Technology Path for APEC 2022
Transformative Role of Power Electronics: In solving climate emergency
Long term shifts in weather patterns and temperature are referred to as climate change. Hotter temperatures, more severe storms, increased droughts, food and water insecurity, and economic disruption, etc. are all due to climate change. According to NASA, “Human activities (primarily the burning of fossil fuels) have fundamentally increased the concentration of greenhouse gases … [Read more...] about Transformative Role of Power Electronics: In solving climate emergency
