Abstract
A winding assembly for a transformer device includes a first and second coil with a plurality of windings, and a first set and a second set of thermally conductive plates. The first and second coils include a plurality of interleaved sets of turns. The plates of the first and second sets of the thermally conductive plates are interleaved with the sets of turns of the first and second coils respectively, and are disposed adjacent to one of the sets of turns of the first and second coils respectively, to transfer heat away from the coils. The first and second coils and the first and second sets of thermally conductive plates are encased in the resin dielectric material.
