Abstract：In order to research the drive and protection circuit of insulated gate bipolar transistor（IGBT），a protection and drive scheme based on automotive standard IC 1ED020I12FTA was designed and implemented on the motor drive system. The protection principle，the gate drive circuit and the selection of gate drive resistance and the EMS design were explained in detail. Finally，a complete experimental system was built and tested. The experimental results show that the designed drive circuit has good switch performance. The motor drive

system with this circuit has high reliability and stability and can output the power the motor needed.
