Recently, the technological progress in manufacturing power devices based on wide bandgap materials, for example, silicon carbide(SiC) or gallium nitride(GaN), has resulted in a significant improvement of the operating-voltage range and switching speed and/or specific on resistance compared with silicon power devices. This paper will give an overview of the status on The Next generation Power Devices such as SiC/GaN with a focus on commercialization and research.
