The present invention relates to an apparatus for controlling a synchronous rectifier of an LDC and an apparatus thereof. The present invention provides the apparatus for controlling a synchronous rectifier of an LDC, capable of completely preventing a reverse powering phenomenon in a very low load environment by not requiring a process of estimating an output current of the LDC by controlling the operation of the synchronous rectifier in the LDC based on an output voltage of the LDC formed in an eco-friendly vehicle, and the method thereof. To this end, the apparatus for controlling a synchronous rectifier of an LDC according to the present invention includes: a receiver for receiving an output command voltage of the low voltage DC-DC converter (LDC); and a controller for controlling the operation of the synchronous rectifier based on the received output command voltage of the LDC.

    본 발명은 LDC의 동기정류기 제어 장치 및 그 방법에 관한 것으로, 친환경 차량에 구비된 LDC의 출력전압에 기초하여 LDC 내 동기정류기의 동작을 제어함으로써, LDC의 출력전류를 추정하는 과정이 필요 없어 극저부하 환경에서도 역파워링 현상을 완벽하게 방지할 수 있는 LDC의 동기정류기 제어 장치 및 그 방법을 제공하고자 한다. 이를 위하여, 본 발명은 LDC의 동기정류기 제어 장치에 있어서, LDC(Low Voltage DC-DC Converter) 출력지령전압을 수신하는 수신기; 및 상기 수신된 LDC 출력지령전압에 기초하여 동기정류기의 동작을 제어하는 제어기를 포함한다.
