In order to enable medium voltage applications at an operation voltage of 5 kV level, a cost-effective 7.2kV/60A Austin SuperMOS SiC power switch is developed. Static and dynamic performance is characterized at various voltage and current levels. Excellent dynamic performance are demonstrated with high dV/dt ranging from 60kV/us and 122kV/us. The output charge of the 7.2kV/60A Austin SuperMOS is also measured to enable accurate loss estimation. Unique gate switching patterns are identified and analyzed for the first time which facilitates the reduction of third quadrant conduction loss during converter deadtime.
