Abstract

The present invention discloses a transformer structure. The transformer structure comprises a first primary winding, and a first secondary circuits. The first secondary circuits comprises a filtering capacitor, a conductive Cu windings and a rectifier configured onto the printed circuit board (PCB) forming the first secondary circuits PCB winding. The first primary winding and the secondary circuits are interleaved with each other.
