Disclosed is a system for supplying charging power using a motor driving system, which comprises: a battery; an inverter which is connected to the battery and includes a plurality of switching devices to change the on/off status of the switching devices, to convert the power stored in the battery, and to output the power to a plurality of output terminals; a motor which includes a plurality of coils which respectively receive power provided from the output terminals of the inverter; the charging power output terminals which are connected to a neutral point commonly connected to the plurality of coils of the motor to output the current output from the neutral point to a subject to be charged in an external side; and a controller which controls the switching devices in the inverter based on the current of output terminal of the inverter to allow the size of the current output from the neutral point to the charging power output terminals to follow a preset current command. The present invention aims to provide the system for supplying charging power using a motor driving system, which is able to reduce costs for building and operating service infrastructure.

    배터리; 상기 배터리에 연결되며, 복수의 스위칭 소자를 포함하고 상기 스위칭 소자의 온/오프 상태를 변경하여 상기 배터리에 저장된 전력을 변환하여 복수의 출력단으로 출력하는 인버터; 상기 인버터의 출력단에서 제공되는 전력을 각각 제공받는 복수의 코일을 포함하는 모터; 상기 모터의 복수의 코일이 공통으로 연결된 중성점에 연결되며 상기 중성점에서 출력된 전류를 외부 충전 대상으로 출력하는 충전 전력 출력단; 및 상기 중성점에서 상기 충전 전력 출력단으로 출력되는 전류의 크기가 사전 설정된 전류 지령을 추종하도록 상기 인버터의 출력단 전류에 기반하여 인버터 내 스위칭 소자를 제어하는 컨트롤러를 포함하는 모터 구동 시스템을 이용한 충전 전력 공급 시스템이 개시된다.
