The proposed method of driving and fast protection of large-capacity IGBT devices can satisfy the drive and short-circuit protection requirements of IGBT devices and power MOSFET devices of various capacities. The principle of driving circuit and fast protection circuit is introduced, and the measurement method of protection circuit response time is introduced. The protection response time under different emission voltages under different reference voltages is simulated. Short-circuit test proved the rapidity of the protection circuit. This drive protection circuit has been used for inverters consisting of 50A / 600V IGBT modules and DC choppers consisting of 400A / 600V IGBT modules. Industrial operation results show that the protection method response time, anti-interference ability.
