Abstract

Charging device for a vehicle, wherein the input side of the charging device (500) comprises an input terminal unit (100) for connecting a single-phase or multiphase alternating voltage and a PFC stage (200) for providing a direct voltage at an intermediate terminal (300), wherein the PFC stage (200) comprises a half-bridge (210, 220, 230) for each phase of the n-phases, wherein a first switching element (S1) is connected on one side to the positive ends of the half-bridges and on the other side to the positive intermediate terminal (310) and being designed to enable or interrupt a current flow between the positive ends of the half-bridges and the positive intermediate terminal (310) via the first switching element (S1).
