Abstract

A planar transformer comprising a printed circuit board; a primary planar winding disposed within the printed circuit board; a secondary planar winding disposed within the printed circuit board; a magnetic material disposed within the printed circuit board between the primary planar winding and the secondary planar winding, the magnetic material configured to generate a secondary magnetic flux path; and a magnetic core disposed around and through the printed circuit board and magnetically coupled to the primary planar winding and the secondary planar winding, the magnetic core configured to generate a primary magnetic flux path.
