A method, apparatus, and article of manufacture for a multi-layer transforme r (132) includes a plurality of layers (168-174) having a magnetic core area (114) disposed on each of the layers forming a magnetic core of the transformer having a prima ry winding (126, 128) disposed on at least one of the layers, and a secondary winding (178, 180) disposed on at least one of the layers. A plurality of interconnecting vias (130) connect t he primary winding between the layers, and a second plurality of interconnecting vias (130) 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.
