Abstract :
Wide bandgap (WBG) power semiconductor devices offer substantial energy efficiency opportunities in a wide range of applications. The Advanced Research Projects Agency-Energy (ARPA-E) has invested in WBG power semiconductor devices since 2010. ARPA-E´s ADEPT (Agile Delivery of Electrical Power Technologies) program, funded several teams to develop a range of SiC and GaN devices and demonstrate their efficacy in power converters. Despite recent progress, high cost remains an important barrier to the widespread adoption of WBG devices. Also, most WBG discrete devices demonstrated to date have had relatively low current ratings.
