Abstract
The primary and/or secondary coils of a relatively high power planar transformer are integrated together with a laminated busbar, thereby incorporating together the planar transformer and the busbar as a single component. A coil is cut out or otherwise formed in at least one busbar conductor, and when electrically connected, the busbar coils act as part of the primary and/or secondary circuit of the transformer. One or more coil lead frames are embedded in the laminated stack, and when electrically connected, form the primary and/or secondary circuit, respectively, of the transformer. Insulating material coils are also embedded within the laminated stack. The center leg of an E-shaped ferrite core passes through the center opening of each of the busbar coils, the coil lead frames, and the insulating material coils. The E-shaped core is located next to (i.e., with an opening) or closed with, an I-shaped or E-shaped core.
