The present invention relates to a power conversion apparatus for supplying an auxiliary power for an ACDC dual voltage electric railway vehicle and a method for supplying the auxiliary power. According to the provided power conversion apparatus for supplying the auxiliary power for the ACDC dual voltage electric railway vehicle and the provided method for supplying the auxiliary power, When converting an electric railway vehicle which uses an existing AC power source to an ACDC dual voltage vehicle, hassle and a cost of newly designing an AC and DC auxiliary power supply can be reduced. As a result, retrofitting of the ACDC dual voltage vehicle is advantageous. The power conversion apparatus for supplying the auxiliary power for the ACDC dual voltage electric railway vehicle of the present invention comprises: a main transformer; an MPU; and an APU.

    본 발명은 교직겸용 전기철도차량을 위한 보조전원 공급용 전력변환장치 및 보조전원 공급방법에 관한 것으로, 기존의 교류 전원을 이용하는 전기철도차량을 교직겸용 차량으로 개조할 때 교류 및 직류 겸용의 보조전원장치를 새롭게 설계해야 했던 번거로움과 비용을 줄일 수 있어 교직겸용 차량의 개조에 유리한 교직겸용 전기철도차량을 위한 보조전원 공급용 전력변환장치 및 보조전원 공급방법을 제공한다.
