The present invention relates to an electronic relay that maintains insulation between a low voltage portion and a high voltage portion and uses a voltage of a low voltage battery to supply power from a high voltage battery to a load. According to an embodiment of the present invention, the electronic relay comprises: a power conversion unit configured to insulate the low voltage portion from the high voltage portion and converting an input voltage applied from the low voltage battery of the low voltage portion into a driving voltage with a different level to output it; and a switching unit connected between the high battery of the high voltage portion and the load and controlling voltage supplying and blocking from the high voltage battery to the load.
본 발명은 저전압단과 고전압단 간의 절연을 유지하면서 저전압 배터리의 전압을 이용하여 고전압 배터리에서 부하로 전원을 공급할 수 있도록 하는 전자식 릴레이에 관한 것이다. 본 발명의 실시예에 따른 전자식 릴레이는, 저전압단과 고전압단을 절연하도록 구성되고 상기 저전압단의 저전압 배터리로부터 인가되는 입력전압을 다른 레벨의 구동전압으로 변환하여 출력하는 전력변환부; 및 상기 고전압단의 고전압 배터리와 부하 사이에 연결되어 상기 고전압 배터리로부터 상기 부하로 전압 공급 및 차단을 제어하는 스위칭부를 포함한다.
