A charging circuit (LS) equipped with a battery terminal (AA), a direct current terminal (GA) and an alternating current terminal (WA), the alternating current terminal being connected to the alternating current side (WS) of the rectifier (G1) of the charging circuit (LS). The DC side (GS) of the rectifier (G1) is connected to the first side (1S) of the DC voltage converter (GW) via a transfer switch (US) which selectively connects the first side (1S) of the DC voltage converter (GW) to the DC termination (GA) or to a first potential (-) of the DC side (GS) of the rectifier (G1). A second potential (+) of the DC side (GS) of the rectifier (G1) is connected to the DC terminal (GA) via a diode (D1). The blocking direction of the diode (D1) points to the DC terminal (GA). The second side (2S) of the DC voltage converter (GW) is connected to the battery terminal (AA), to which the DC terminal (GA) is connected via a disconnector (TS1). A vehicle electrical system having a charging circuit is also described.

    充电电路(LS),配备有蓄电池终端(AA)、直流终端(GA)和交流终端(WA),交流终端联接在充电电路(LS)的整流器(G1)的交流侧(WS)。整流器(G1)的直流侧(GS)经由转换开关(US)与直流电压转换器(GW)的第一侧(1S)连接,转换开关(US)将直流电压转换器(GW)的第一侧(1S)选择性地与直流终终端(GA)或与整流器(G1)的直流侧(GS)的第一电位(‑)连接。整流器(G1)的直流侧(GS)的第二电位(+)经由二极管(D1)与直流终端(GA)连接。二极管(D1)的阻断方向指向直流终端(GA)。直流电压转换器(GW)的第二侧(2S)与蓄电池终端(AA)连接,直流终端(GA)经由隔离开关(TS1)连接到蓄电池终端。还描述了具有充电电路的车辆电气系统。
