배터리와, 모터 구동 시 상기 배터리에 저장된 직류 전력을 입력 받아 3상 교류로 변환하여 상기 모터로 출력하는 인버터와, 상기 인버터에서 출력되는 3상 교류 전력을 이용하여 회전력을 생성하는 상기 모터를 포함하는 모터 구동 시스템을 이용한 충전 시스템으로서, 상기 모터의 중성점으로 외부 충전 전류가 제공되는 경우 상기 인버터 내 스위칭 소자의 듀티를 결정함으로써 상기 모터의 중성점 전압을 승압하여 상기 배터리로 출력하도록 인버터를 제어하는 컨트롤러를 포함하는 모터 구동 시스템을 이용한 충전 시스템이 개시된다.

    A charging system using a motor driving system, the motor driving system including: a battery and an inverter, the inverter configured to receive and convert a direct current (DC) power stored in the battery into a three-phase alternating current (AC) power and to output the three-phase AC power to a motor when the motor is driven and the motor configured to generate a rotation force using the three-phase AC power output from the inverter, the charging system includes a controller configured to control the inverter to boost a voltage at a neutral point of the motor and to output the boosted voltage to the battery by determining duty values of switching elements in the inverter when an external charging current is provided to the neutral point of the motor.
