Abstract
A method, apparatus, and article of manufacture for a multi-layer transformer includes a plurality of layers having a magnetic core area disposed on each of the layers forming a magnetic core of the transformer having a primary winding disposed on at least one of the layers, and a secondary winding disposed on at least one of the layers. A plurality of interconnecting vias connect the primary winding between the layers, and a second plurality of interconnecting vias connect the secondary winding between the layers. The interconnecting vias are disposed proximate a center of the magnetic core of the transformer, thus, reducing the overall volume, size, weight, and cost of a transformer while meeting regulatory isolation safety requirements.
