Webimportant failure is the failure of one IGBT module. This failure can happen during the current commutation from the load current path to the main breaker. If one position fails the IGBT module goes to short circuit failure mode and the hybrid DC breaker can still interrupt the fault current, but the positions beside it shall survive. WebThat is a common failure mode resulting from short overvoltage spikes. As I said before, a IGBT is not the best choice here. There is no reason you need a FET to drive the NPN inside the IGBT for you. You can modify the circuit a bit to drive a NPN directly.
