ABSTRACT:
A multi-winding a-c electric power supply is connected to a d-c load circuit via a power rectifier assembly comprising at least two legs connected in parallel across the load circuit. Each leg has at least four serially interconnected unilaterally conducting devices. A first one of the power supply windings is connected between the two rectifier legs at points between first and second devices thereof, and a duplicate winding (voltages of both windings are in-phase and of equal amplitude) is connected between the legs at points between third and fourth devices thereof, whereby the windings are effectively connected in parallel. The respective junctures of the second and third devices in all of the rectifier legs are interconnected by switching means which, upon switching to a closed circuit state, short circuits these junctures and thereby changes the connection of the windings from parallel to series.
