Abstract

Higher power density, higher operational temperature, lower on state resistance and higher switching frequency capabilities of Silicon Carbide (SiC) technology devices compared to Silicon (Si) devices makes it has higher promising market. One of the most developed SiC devices is the power MOSFET. This study tests the SiC MOSFET under short circuit conditions taking into account the effect of gate voltage characteristics. The results will be compared to IGBT and MOSFET Si devices with similar ratings. A tester circuit was designed to perform the short circuit operation.
