Abstract
A power converter includes a first transformer that has a primary winding and a secondary winding. The secondary winding is coupled to a first secondary side. A second transformer has a primary winding and a secondary winding. The secondary winding is coupled to a second secondary side. The primary windings of the first and second transformers are coupled in parallel to a primary side through respective windings of a transformer that has inverse coupled windings. The secondary windings of the first and second transformer are coupled in parallel. The second secondary side is interleaved with the first secondary side.
