Abstract

An alternating voltage charging device for a vehicle is equipped with a rectifier, a battery terminal, and at least one first DC link capacitor, which is provided between the rectifier and the battery terminal. The charging device includes a switch device, which connects at least one second DC link capacitor to the at least one first DC link capacitor. The switch device interconnects the DC link capacitors in parallel in a first switching state and in series in a second switching state. There is also described a method to be carried out by the charging device.
