Disclosed is a vehicle mounted-type charging system capable of minimizing ripple of an input alternating current by interlocking operation timings of switching circuits in each of a charging circuit when a plurality of charging circuits are connected in parallel between input and output terminals. The vehicle mounted-type charging system has a power factor correction circuit part for correcting a power factor of an alternating current input power by pulse width modulation control of a switching element, and comprises: a plurality of charger circuits connected in parallel to each other between an input terminal of the alternating current input power and an output terminal connected to a charging object; and a controller for interlocking the switching element to generate a pulse width modulation control signal for performing pulse width modulation control.

    복수의 충전 회로가 입출력단 사이에 병렬로 연결되는 경우 각 충전 회로 내의 스위칭 회로의 동작 타이밍을 상호 연동시킴으로써 입력 교류 전류의 리플을 최소화할 수 있는 차량 탑재형 충전 시스템이 개시된다. 상기 차량 탑재형 충전 시스템은, 스위칭 소자의 펄스폭 변조 제어에 의해 교류 입력 전력의 역률을 보정하는 역률 보정 회로부를 가지며, 상기 교류 입력 전력의 입력단과 충전 대상과 연결된 출력단 사이에 상호 병렬관계로 연결된 복수의 충전기 회로; 및 상기 스위칭 소자를 상호 연동시켜 펄스폭변조 제어하는 펄스폭변조 제어신호를 생성하는 컨트롤러를 포함한다.
