Wide bandgap (WBG) power devices and their impacts on power delivery systems

摘要

Wide bandgap (WBG) power semiconductor devices have the capability to reach higher voltage, higher frequency and higher temperature compared with silicon based power devices. These capabilities have the potentials to revolutionize the way we deliver and manage power in the future. This paper reviews the WBG progress and their potential transformative impacts on low voltage, medium voltage and high voltage power delivery systems.
