The utility model provides an IGBT (Insulated Gate Bipolar Transistor) trigger device with redundancy function, which comprises a PWM (Pulse-Width Modulation) signal correctness detection circuit, a dead area time control circuit, a redundant push-pull trigger circuit and a protection circuit; the reliable opening and off of the IGBT are ensured by detecting the PWM trigger signal and setting the time in the dead area of the IGBT; the redundant push-pull trigger circuit comprises a pair of push… CONTINUE READING
