Claim 14:
15. The device of claim 14, wherein the planar transformer comprises:
a core that is less than 6.5 mm in height;
a primary circuit comprising: a plurality of primary coils on printed circuit boards (PCBs) integrated with the core, each in a spiral shape having a center and an outer end, respective outer ends of a first primary coil and a last primary coil in communication with the chopper circuit, wherein adjacent primary coils are connected either center-to-center or outer end-to outer end, such that the plurality of primary coils form the primary circuit as a first continuous circuit in a same spiraling direction around a central portion of the core;
a secondary circuit comprising: a plurality of secondary coils around the core, each in a circular shape and connected to form the second circuit as a second continuous circuit around the central portion of the core, respective ends of a first secondary coil and a last secondary coil in communication with the rectifier; and
insulating material between each of the plurality of primary coils and the plurality of secondary coils.
