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.
An apparatus for controlling a converter includes: a failure detector that detects failure of a sensor included in an input or output side of the converter, a substitution factor calculator that calculates a substitution factor based on a measurement value of a sensor in a high voltage battery connected to an input side of the converter when failure is detected in the sensor of the input side by the failure detector and calculates the substitution factor based on measurement values of a sensor connected to one or more loads when failure is detected in the sensor of the output side, and an emergency operation controller that controls an operation in a constant current or constant voltage scheme based on the calculated substitution factor.
