The invention relates to a charger for a vehicle, said charger (500) comprising, on the input side, an input connection unit (100) for connecting a multi-phase alternating voltage; and a PFC stage (200) for providing a DC voltage at an intermediate connection (300), in which a second connection line (120) is divided into a first part (1201) of the second connection line and a second part (1202) of the second connection line, in which a second switching element (S2) is provided for switching the first part (1201) of the second connection line and the second part (1202) of the second connection line. The second switching element is arranged between the first part (1201) of the second connection line and the second part (1202) of the second connection line and is configured to conduct a charging current from the second input connection (L2) to the second choke (204) via the first and second parts (1201, 1202) of the second connection line, or a charging current is conducted from the first connection line (110) to the second choke (204) via the second portion (1202) of the second connection line.
一种用于车辆的充电器,其中,所述充电器(500)在输入侧包括:输入端连接单元(100),用于连接多相交流电压;和PFC级(200),用于在中间连接端(300)处提供直流电压,其中,第二连接线路(120)被划分成所述第二连接线路的第一部分(120_1)和所述第二连接线路的第二部分(120_2),其中,提供第二开关元件(S2),所述第二开关元件布置在所述第二连接线路的所述第一部分(120_1)与所述第二连接线路的所述第二部分(120_2)之间,而且被设立为:将充电电流从所述第二输入连接端(L2)经由所述第二连接线路的第一部分和第二部分(120_1、120_2)传导到所述第二扼流圈(204),或者将充电电流从所述第一连接线路(110)经由所述第二连接线路的所述第二部分(120_2)传导到所述第二扼流圈(204)。
