A rectifier circuit has one or more bridge circuits each with: a first leg with two diodes in series and an AC terminal at a midpoint between the two, a second leg with two semiconductor switches in parallel to the first, a third diode connected to a upper node of each leg, a fourth diode connected to a lower node of each leg, and a capacitor leg with two capacitors in series between the third and fourth diode. A midpoint between the capacitors is connected to a midpoint between the semiconductor switches. The first arrangement is two controllable semiconductor switches in series. A gate node of the second is connected to a first load terminal of the first switch and the first load terminal is connected to the lower node. The second semiconductor switch is a third controllable semiconductor switch with a gate node connected to the lower node.
