Abstract: An example power converter may include a planar transformer including a magnetic core, a primary winding, a first secondary winding interleaved with the primary winding, and a second secondary winding interleaved with the primary winding. The magnetic core may include a first core half, a second core half, multiple auxiliary legs formed by the first core half and the second core half, and multiple core legs formed by the first core half and the second core half. The multiple core legs may include a central core leg, and the primary winding may be wound around the central core leg among the two or more core legs. The planar transformer may be electrically coupled between a primary-side converter stage and a secondary-side converter stage.
