Suppression of Short-Circuit Current with Embedded Source Resistance in SiC-MOSFET

Abstract:

Article Preview

This work reports an SiC-MOSFET which replaces a part of the channel resistance with an additional embedded resistance, called a source resistance (Rs). MOSFETs with Rs have higher resistance during short circuit compared with MOSFETs without Rs and suppress short-circuit currents. An improvement of the trade-off relationship between short-circuit capability and on-resistance was obtained with MOSFETs including embedded Rs.
