Abstract
A circuit arrangement for providing a DC voltage in a vehicle and a method for operating the circuit arrangement. The circuit arrangement includes at least one secondary-sided inductance of a vehicle-sided pick-up portion for receiving a magnetic field and for producing an electric output voltage, at least one rectifier for rectifying the output voltage of the at least one inductance, and at least one source element or drain element. The rectifier and the source element are connected such that an output voltage of the circuit arrangement is a sum of an output voltage of the rectifier and an output voltage of the source element or the rectifier and the drain element are connected such that an output voltage of the circuit arrangement is a difference between an output voltage of the rectifier and an input voltage of the drain element.
