ABSTRACT:
A drive transformer for use in a p.w.m. power supply which has alternately conducting power switching devices. The single transformer includes a primary winding, a secondary winding and a regenerative winding. When one of the devices finally becomes nonconductive the other of the devices may turnon. The regenerative winding aids the conduction of that device and also reinforces the drive signal to the device which receives from the drive circuitry of the supply a turnon drive signal.
