The present invention relates to a charging device for a vehicle. Specifically, the present invention relate to a technique for effectively controlling a converter which charges a battery used for a hybrid electric vehicle or fuel electric vehicle. The charging device for a vehicle includes a boost converter which converts AC power applied to a power node into DC power, and a DC/DC converter which converts DC power applied to the boost converter into a battery charging voltage and supplies the converted voltage to the battery. The DC/DC converter resonates a capacitor which is formed in a snubber circuit and a leakage inductance generated in a primary coil part.
본 발명은 차량용 충전 장치에 관한 것으로, 특히 하이브리드 전기 차량 또는 연료 전지차 등에 채용되는 배터리를 충전하는 컨버터를 효율적으로 제어할 수 있도록 하는 기술이다. 이러한 본 발명은, 전원노드에 인가된 교류 전원을 직류 전원으로 변환하는 부스트 컨버터, 및 부스트 컨버터로부터 인가되는 직류 전원을 배터리 충전전압으로 변환하여 배터리에 공급하는 DC/DC 컨버터를 포함하고, DC/DC 컨버터는 일차코일 측에서 발생한 누설 인덕턴스와 스너버 회로에 구비된 커패시터를 공진시키는 것을 특징으로 한다.
