A power converter for converting an input voltage (Vin) into an output voltage (Vout), comprising a first supply potential and a second supply potential established by the input voltage, and at least one primary winding having two terminals, a center tap arranged between the two terminals and connected to the first supply potential, and at least one secondary winding magnetically coupled to the primary winding for providing at least one output voltage (Vout) and a first controllable switch connected between the second supply potential and one terminal of the primary winding and a second controllable switch connected between the second supply potential and the other terminal of the primary winding and a third controllable switch connected between the second supply potential and the one terminal of the primary winding and a fourth controllable switch connected between the second supply potential and the other terminal of the primary winding, and a control unit for controlling the switches such that the first, second, third, and fourth switches are turned on sequentially wherein at any time maximum one switch is turned on.
