Abstract

The invention relates to an over voltage protection apparatus for a power conversion apparatus for a vehicle and a method thereof. The over voltage protection apparatus according to the invention comprises the components of a current sensor which detects the current value of a vehicular electric power converter device; a control part which outputs a control signal when an overvoltage is determined in the vehicular electric power converter device according to the current value that is detected by the current sensor; and a protective part which reduces the overvoltage in the vehicular electric power converter device according to the output control signal.

Description

Technical field [0001] The present invention relates to an overvoltage protection device for a power conversion device for a vehicle and a method thereof, and more specifically, a device and method for protecting a power conversion device for a vehicle from an overvoltage caused by a structural problem of an inverter. Background technique [0002] Generally speaking, the power conversion device of a hybrid electric vehicle is used to control the electric energy required by the electric power train (ElectricPowerTrain), including an inverter and a converter. [0003] The inverter receives power from the high-voltage battery to drive an electric motor for assisting the engine of the hybrid vehicle, and during regenerative braking, receives the power from the electric motor to charge the high-voltage battery. [0004] The converter converts the electric energy stored in the high-voltage battery into a low-voltage, and charges the low-voltage battery, such as a 12V battery, that supplies...
