Abstract (en)

A planar transformer (300) includes an "E" core (106) having first (128) and second (130) windows and a central core leg (110). First (320) and second (322) conductive plates are threaded through the first and second windows to encircle the central core leg. The first and second conductive plates are disposed substantially in parallel and define first and second electrical paths, respectively, around the central core leg. First (324) and second (326) transverse conductor portions connect the first and second conductive plates such that a first end of the first electrical path is connected to a first end of the second electrical path, and a second end of the first electrical path is connected to a second end of the second electrical path, whereby a parallel electrical connection is established between the first and second conductive plates. A third conductor (314) is threaded through the first and second windows to encircle the central core leg. The third conductor is disposed between the first and second conductive plates. <IMAGE>
