Reviewing of Using Wide-bandgap Power Semiconductor Devices in Electric Vehicle Systems: from Component to System

摘要

The application of wide-bandgap (WBG) power semiconductor devices (silicon carbide and gallium nitride) in EV power electronics systems has a huge potential to increase EV efficiency, reliability and mileage. However, they extend cutting-edge research where both opportunities and challenge exist. In order to look for different approaches to address the research challenge, WBG power semiconductor devices and their application in electrical vehicle systems is reviewed in this paper, which will eventually benefit designers to choose appropriate devices and methodologies to improve EV power electronics systems performance.
