본 발명은 특히 전기 또는 하이브리드 차량에 온-보드(on-board) 방식으로 설치되도록 설계된 전기 시스템과 관련된 것으로, 상기 전기 시스템은: 정류기(RD)를 포함하는 AC-대-DC 컨버터; DC-대-DC 컨버터(DC, DCDC2, DCDC20); 및 고 전압 배터리(HV)에 연결된, 격리된 DC-대-DC 컨버터(LLC)를 포함하며, 상기 전기 시스템은 제 1 동작 모드에서 상기 고 전압 배터리(HV)를 충전하기 위해 외부 교류 전기 그리드(G)에 연결되도록 구성된다. 또한, 상기 DC-대-DC 컨버터(DCDC20)의 상기 제 1 인터페이스 단자들은 저 전압 배터리(LV)에 접속되며, 상기 전기 시스템은 제 2 동작 모드에서, 상기 외부 교류 전기 그리드(G)로부터 분리될 때, 상기 DC-대-DC 컨버터(DCDC20)는 고 전압 배터리로부터의 초기 전압(V1, V2)을 공급하여 저 전압 배터리(LV)에 전력을 공급하도록 구성된다.

    The present invention pertains to an electrical system, in particular designed to be installed on board an electric or hybrid vehicle, whereby said electrical system includes an AC-to-DC converter that includes a rectifier and a DC-to-DC converter, an isolated DC-to-DC converter connected to a high voltage battery, and whereby said electrical system is configured, in a first operating mode, to be connected to an external alternating electricity grid to charge the high voltage battery. Furthermore, the first interface terminals of the DC-to-DC converter are connected to a low voltage battery, whereby said electrical system is configured so that, in a second operating mode, when the electrical system is disconnected from the external alternating electricity grid, said DC-to-DC converter supplies an initial voltage from the high voltage battery to power the low voltage battery.
