ABSTRACT:
A power supply for supplying a main electrical circuit during normal operation and an auxiliary electrical circuit during standby operation, includes a switched power converter, which is connected between an input voltage and the main electrical circuit and has an inductor, a controllable switch, a first rectifying unit and a control unit for the switch. A second rectifying unit couples the voltage dropping across the inductor into the auxiliary electrical circuit. During standby operation, the control unit controls the switch in such a way that the switched power converter is operated in resonance mode.
