Double Side Cooled Modules Enable Future Generation of SiC-Traction-Inverters

In order to utilize the full capabilities of silicon carbide MOSFETs in automotive inverters, various aspects must be considered. Understanding wide bandgap (WBG) semiconductor materials, efficiency, smaller packages and high-power density, EMC challenges, lowest unit price and integrability are some of these aspects. All these points are highly in competition with each other. This paper shows a SiC-Traction-Inverter with double side cooled (DSC) modules, that optimizes this seemingly incompatible points in a structured manner. An innovative solution uses double side cooled modules as an enabler to raise the compatibility of the above factors to a balanced optimum, resulting in a future-proof and market-driven DC/AC converter for the automotive market.
