High-Density Power Conversion and Wide-Bandgap Semiconductor Power Electronics Switching Devices

摘要

Power electronics switching devices made on wide-bandgap (WBG) semiconductors are known to have the potential to make a transformative impact on 21st century energy economy. However, their market penetration has been slow primarily due to high cost and unknown application-level reliability. This article presents a comprehensive report on the history, current state of the art, and impending challenges in WBG power semiconductor technologies in order to break open this gridlock.
