The evaluation and application of wide bandgap power devices

This paper presents an overview of wide bandgap (WBG) power devices. The development and challenges of silicon carbide (SiC) and gallium nitride (GaN) power devices are summerized. A comprehensive evaluation of the performance of different devices is conducted, including static characterization and dynamic switching related tests. The paper also demonstrates the application of WBG devices in power electronic circuits. The testing results are provided to show the performance of WBG devices in different aspects.
