Abstract
An inverter for supplying electrical energy from a DC supply to a load, includes a flyback transformer having a primary winding circuit coupled to the DC supply, and a secondary winding circuit coupled to the load. The primary winding circuit includes a first switch for interrupting the DC supply causing energy to be stored in the transformer, and the secondary winding circuit includes a second, unidirectional switch to produce an output of one sign when closed. The primary winding circuit further includes an electrical device effective to return energy to the DC supply only when the first and second switches are open.
