Abstract
A quasi-planar transformer can include a first winding comprising one or more turns of wire, a second winding comprising one or more turns of a conductive trace disposed on a printed circuit board, and a magnetic core positioned with respect to the first and second windings so as to provide a magnetic flux path coupling the first and second windings. The first winding can be a primary winding having a first half wound in a clockwise direction on a first side of the printed circuit board and a second half wound in a counterclockwise direction on a second side of the printed circuit board, wherein the first and second halves are formed of a single continuous wire. The single continuous wire can pass through an opening in the printed circuit board. The first and second halves of the primary winding can be secured to the printed circuit board.
