Abstract
In one embodiment of the present invention, a transformer includes a first secondary winding made of stamped and bent metal. This first secondary winding has a coil portion with substantially closed cross section. The transformer also includes a primary winding made of wire and having a coil portion wound around the coil portion of the first secondary winding. A second secondary winding made of stamped and bent metal and having a coil portion with substantially closed cross section has its coil portion disposed about the coil portion of the primary winding. The primary winding further includes a second coil portion wound around the coil portion of the second secondary winding. The transformer thus provided is easier to build and less apt to internal short-circuiting than alternative designs.
