Abstract: The present invention relates to a circuit arrangement having an active rectifier circuit, in particular on a secondary side of an inductive energy transmission path. The circuit arrangement has a half or full bridge of power transistors for rectifying an AC voltage induced in an input inductor of the circuit arrangement. The power transistors are connected to the input inductor in such a way that an auxiliary voltage is split off from the induced AC voltage for switching the power transistors. As a result, even large currents, which result in a low output voltage, can be transmitted without endangering the operation of the rectifier circuit.
