An apparatus for controlling a converter according to the present invention includes a failure detection part which detects the failure of a sensor formed in the converter, calculates a substitute factor based on a sensor measurement value in a high voltage battery connected to the input part of the converter when the failure is detected in the input part of the sensor according to failure detection, and calculates a substitute factor based on a sensor measurement value connected to at least one load when the failure is detected in the output part of the sensor, and an abnormal operation control part which controls an operation by a constant voltage or constant current mode based on the calculated substitute factor. So, the reliability and stability of an entire vehicle system can be secured.
본 발명에 따른 컨버터 제어 장치는, 컨버터에 구비된 센서의 고장을 검출하는 고장 검출부, 고장 검출에 따라 입력 측 센서에서 고장이 검출된 경우에는 컨버터의 입력 측과 연결된 고전압 배터리 내 센서 측정 값에 기초하여 대체인자를 산출하고, 출력 측 센서의 고장인 경우에는 적어도 하나의 부하에 연결된 센서 측정 값에 기초하여 대체인자를 산출하는 대체인자 산출부, 및 산출된 대체인자에 기초하여 정전압 또는 정전류 방식으로 동작을 제어하는 비상동작 제어부를 포함한다.
