Abstract

A vehicle-side circuit for supplying power in an electrically driven vehicle is provided. The power circuit includes an external AC voltage terminal; at least one DC/AC converter having an AC voltage side; and an electrical machine having a plurality of windings, each of which has a first tapping. The electrical machine is connected to the AC voltage side of the DC/AC converter. A switching device is connected to the plurality of windings and to a signal shaping filter having a plurality of first capacitors. The signal shaping filter is connected between the DC/AC converter and an external AC terminal. The switching device may interconnect the windings within the electrical machine or may connect the first tappings of the plurality of windings within the signal shaping filter to the plurality of first capacitors to form an at least third-order low-pass filter.
