ABSTRACT:
A first AC/DC converter circuit is coupled via two transformers to a second AC/DC converter circuit, the first AC/DC converter circuit having a symmetrical configuration of two switching elements performing complementary opened/closed switching, to alternately connect positive and negative terminals of a DC source to a junction between transformer primary windings. Each primary winding alternates between a condition of transferring electrical power to a secondary winding and a condition of serving as a choke coil which temporarily stores electromagnetic energy when a current flows through that primary winding and a primary winding of the other transformer.
