A rectifier circuit is disclosed comprising input terminals adapted to receive an alternating current voltage,and output terminals adapted to provide an output having a rectified output voltage. The rectifier circuit has a diode bridge in which the diodes are each adapted to be by-passed by a low-impedance path on activation of an associated electronic switching device (Q1,Q2,Q3,Q4). Furthermore, the rectifier circuit is adapted to control activation of one or more electronic switching devices(Q1,Q2,Q3,Q4), such that the flow of current relative to one of the output terminals is in one direction only. |
