This paper describes a compact SiC power module for a 2 in 1 half bridge circuit, free from external fly-wheeling diodes. A new class of SiC MOSFET called DioMOS not only functions as a MOSFET but also as a reverse diode by utilizing an n-type epitaxial channel under the MOS gate for the reverse conduction path. Elimination of external diodes allows the size of the module to be reduced by half in the footprint, which can be very promising for various industrial applications. The current rating and blocking voltage of the module are 100A and 1200V, respectively.
