Automotive Traction Inverter Utilizing SiC Power Module

In 2010, the first Silicon Carbide (SiC) power transistor was launched to the market. This initiated a revolution in the power electronic field and is leading to an increasing rate of SiC devices adoption in many industrial and automotive application fields which proved that SiC components are strong competitors to classical Si devices in such applications. Electric Vehicle (EV) applications represent a big potential area where the adoption of high performance SiC power devices can provide benefits. This paper focuses on presenting the benefits of a newly developed SiC power module and the utilization of this module in a power train inverter. A comparison of the performance of the SiC based inverter with a Si based traction inverter is also shown in this paper.
