Abstract
A device for protecting a converter and a control method thereof, the device including: a voltage detection unit that detects at least one of an input-stage voltage and an output-stage voltage of a converter; a switching device that connects an output stage of the converter and a load connected to the output stage, or blocks a connection; a controller that determines whether the detected input-stage voltage or output-stage voltage is out of a preset voltage range, and, when the voltage is out of the range, controls the switching device to cut off the connection between the output stage of the converter and the load; and a driving unit that controls an operation of at least one of the fuel cell and the battery so that a driving force of the vehicle is not generated by the fuel cell and the battery when the connection is cut off.
