| Abstract: | A novel driving circuit with three-stage method and a new protection circuit are designed for the Reverse Blocking IGBT. This scheme can reduce the RB-IGBT switching transition substantially without causing the increase of di/dt in turn-on transition and dv/dt in turn-off transition. In order to verify the feasibility of the driving and protection circuit for RB-IGBT, an AC-AC Buck chopper is constructed. Four kinds of commutation strategies are analyzed and tested on the chopper |
