DEVICE AND METHOD FOR PROTECTING INVERTER OF ELECTRIC VEHICLE

摘要

PURPOSE: An inverter protecting apparatus of an electrical vehicle and a method thereof are provided to prevent the damage to the inverter by blocking the power in case the inverted voltage is applied between the high voltage inverter and the high voltage battery. CONSTITUTION: An inverter(140) converts the DC power supplied from a battery into the AC signal and applies it to a motor(150). An auxiliary relay(120) is turned on according to the control signal and supplies the initial power to the battery. A reverse voltage detection unit(160) compares the voltages outputted from the both ends of the battery and compares those.
