The present invention relates to an electric vehicle and a charging device of the electric vehicle. The charging efficiency of the charging device is improved by reducing switching losses which may occur in the charging device of the electric vehicle. To this end, a power factor correction device of an on-board charger according to the present invention comprises: a first boost circuit which receives AC power through a first inductor and charges a load; a second boost circuit which receives the AC power through a second inductor and charges the load; and a third inductor provided between a leg of the first boost circuit and a leg of the second boost circuit so that parasitic capacitors of the first boost circuit and the second boost circuit are discharged.

    본 발명은 전기 자동차 및 전기 자동차의 충전 장치에 관한 것으로, 전기 자동차의 충전 장치에서 발생할 수 있는 스위칭 손실을 줄여서 충전 장치의 충전 효율을 개선하는데 그 목적이 있다. 이를 위해 본 발명에 따른 차량 탑재 충전기의 역률 보정 장치는, 제 1 인덕터를 통해 교류 전력을 입력받아 부하를 충전하는 제 1 부스트 회로와; 제 2 인덕터를 통해 상기 교류 전력을 입력받아 상기 부하를 충전하는 제 2 부스트 회로와; 상기 제 1 부스트 회로 및 상기 제 2 부스트 회로의 기생 캐패시터가 방전되도록 상기 제 1 부스트 회로의 레그와 상기 제 2 부스트 회로의 레그 사이에 마련되는 제 3 인덕터를 포함한다.
