Abstract
In this work the short circuit behaviour of two models of Silicon Carbide MOSFETs, rated 1.2 kV 36 and 90 A are analysed. The static characterization of several devices of each model has been performed. Of each model, the devices with highest and lowest drain-source leakage current were selected for short-circuit testing. The behaviour at different DC-link voltage and case temperature has been performed. Additionally, the failure mode, the calculated gate drop, short circuit energy and a simulation of the junction temperature is presented.
