Beschreibung
Zusammenfassung:	The present invention relates to a direct current (DC)-direct current (DC) converter connected to a high voltage battery and a lower voltage battery, and charging the low voltage battery by converting high voltage of the high voltage battery into low voltage battery. The DC-DC converter comprises: a connection unit in which the high voltage battery and the low voltage battery are connected; a conversion unit for converting high voltage supplied from the high voltage battery into low voltage to charge the low voltage battery; and a protection circuit positioned between the connection unit and the conversion unit, and turned off to block a current path between the high voltage battery and the low voltage battery when any one from the high voltage battery and the low voltage battery is misconnected. Therefore, a disconnection situation can be prevented when a battery is misconnected to the DC-DC converter. 본 발명은 고전압 배터리 및 저전압 배터리와 연결되어, 고전압 배터리의 고전압을 저전압으로 변환하여 저전압 배터리를 충전하는 DC-DC 컨버터에 관한 것으로, 상기 DC-DC 컨버터는 상기 고전압 배터리와 상기 저전압 배터리가 연결되는 접속부; 상기 고전압 배터리로부터 공급되는 고전압을 저전압으로 변환하여 상기 저전압 배터리를 충전하는 변환부; 및 상기 접속부와 상기 변환부 사이에 위치하여, 상기 고전압 배터리 및 상기 저전압 배터리 중 적어도 하나가 오접속 되는 경우 턴 오프 되어 상기 고전압 배터리와 상기 저전압 배터리 사이의 전류 경로를 차단하는 보호회로를 구비한다.
