본 발명은 차량용 충전기에 관한 것으로, 상용 교류전원을 직류전원으로 변환하는 AC/DC 컨버터와, 상기 AC/DC 컨버터로부터 인가되는 상기 직류전원을 배터리 충전전원으로 변환하여 배터리로 공급하는 DC/DC 컨버터를 포함하고, 상기 DC/DC 컨버터는 상기 충전전원의 리플(ripple) 전류 크기를 저감시키는 스너버 회로를 포함한다.

    A device and method are provided for a charger for vehicles. In particular, the charger includes, an AC/DC converter configured to convert a commercial alternating current power source to a direct current power source and a DC/DC converter configured to convert the direct current power source applied from the AC/DC converter to a battery charging power source. The direct current power source is supplied to a battery. The DC/DC converter includes a snubber circuit that reduces the magnitude of a ripple current of the charging power source.
