Abstract

A power converter has a power switching stage which includes an output transformer containing a primary winding and a secondary winding, as well as structure for switching the current flowing through the primary from a first direction to a second direction. A feedback circuit is provided for feeding back a voltage proportional to a portion of the voltage across the primary winding on said output transformer to the structure for switching, to regeneratively turn on the switch and maintain the current flowing through the primary in the direction to which the current has been switched until the current is turned off. To help start the current through the primary in one direction or the other direction, structure is provided which supplies a pulse to the structure for switching, to positively start the current flowing in the desired direction through the primary. Because the power switching stage of a power converter uses primary and secondary windings, a novel structure is provided for the formation of these windings to insure their proper coupling.
