Sic mosfet body diode reverse recovery
Web1.1.2. dv/dt ramp during the diode reverse recovery When inverters and other circuits with an inductive load have a pair of MOSFETs in the upper and lower arms, a current flows … WebOne of the issues of SiC MOSFET is the reliability of its intrinsic body diode when used as a free-wheeling diode (FWD). The reverse current through the SiC MOSFET may cause 4 â á degradation over time. A new structure of a SBD-embedded MOSFET has been proposed that prevents the current conduction through its intrinsic body diode.
