The invention discloses an electric automobile power driving module, and relates to the technical field of power electronics. A first insulated gate bipolar transistor and a second insulated gate bipolar transistor is formed in parallel to the A-phase control circuit, a third insulated gate bipolar transistor and a fourth insulated gate bipolar transistor B is formed in parallel with the control circuit, the fifth insulated gate bipolar transistor and a sixth insulated gate bipolar transistor in parallel to form a C-phase control circuit; between the gate and the emitter of each insulated gate bipolar transistors are connected to a freewheeling diode; in the a phase control circuit, B and C phase control circuit with the input of the control circuit is provided with optocouplers and a set of bootstrap capacitor. It can solve the existing power module peripheral circuit complexity, more connections, resulting in more problems hidden faults.
