Abstract: A method for protecting a capacitor of an inverter is provided to protect a capacitor easily without an additional hardware by applying a zero voltage vector application logic to PWM. An inverter includes a plurality of switching device(S1-S6), which is divided into an upper group and a lower group. If a failure is generated at a motor in high operation HEV(Hybrid Electric Vehicle), a zero voltage vector is applied to a plurality of switching devices. At that time, the zero voltage vector is applied to the upper and the lower group alternately to reduce the stress of IGBT(Insulated Gate Bipolar Transistor). Switching device and a motor equivalent circuit form a close circuit, counter electromotive force from rotation of an engine is generated at the motor in engine drive mode. The counter electromotive force is flowed into the inverter through the equivalent circuit and is consumed in the closed circuit.
