The status and future of silicon carbide

In this paper we discuss the status of a new class of high performance power switching device that is built with semiconductor silicon carbide (SiC). The potential impact on advanced electrical power systems of Sic is discussed and results show SiC switches and diodes with nearly ideal and high speed switching behavior. A hybrid power bridge, a silicon switch with a SiC diode, shows circuit efficiency improving from 88 to 92%.
