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 single-phase or multi-phase alternating voltage; the invention relates to a power converter (100) comprising n phases, a positive intermediate connection (310), and a PFC stage (200) for providing a DC voltage at the intermediate connection (300), the PFC stage (200) comprising, for each of the n phases, a half-bridge (210, 220, 230), a first switching element (S1) being connected on the one hand to a positive end of the half-bridge and on the other hand to the positive intermediate connection (310), and a second switching element (S2) being connected on the other hand to a negative end of the half-bridge (210, 220, 230) to a negative end of the half-bridge (210, 220, 230). The first switching element (S1) is configured to enable or interrupt a current flow between the positive end of the half-bridge and the positive intermediate connection (310).
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),用于连接单相或多相交流电压;和PFC级(200),用于在中间连接端(300)处提供直流电压,其中,所述PFC级(200)针对所述n相中的每一相都包括半桥(210、220、230),其中,第一开关元件(S1)一方面与所述半桥的正端连接,并且另一方面与所述正中间连接端(310)连接,而且被设立为:通过所述第一开关元件(S1)来启用或中断所述半桥的正端与所述正中间连接端(310)之间的电流流动。
