A magnetic assembly includes a magnetic core including at least one winding leg and at least one winding. The at least one winding inductively coupled to the magnetic core and wound around the at least one winding leg. The at least one winding includes a foil conductive material and a tape. The tape includes a thermally conductive adhesive layer and an electrically insulating layer.

Foil wound magnetic assemblies with thermally conductive tape and methods of assembling same

At least one embodiment of a power supply includes a printed circuit board formed from a plurality of double-sided laminates and a plurality of thermally conductive, electrically insulating pre-preg sheets interleaved with the plurality of double-sided laminates. Each double-sided laminate illustratively includes an electrically insulating core, a first patterned layer of electrically conductive material arranged on a first side of the electrically insulating core, and a second patterned layer of electrically conductive material arranged on a second side of the electrically insulating core opposite the first side. The printed circuit board illustratively further includes a thermally conductive, electrically insulating additive resin filling spaces between the electrically conductive material in both the first and second patterned layers of each of the plurality of double-sided laminates, such that the electrically conductive material and the additive resin together form planar surfaces that contact the plurality of pre-preg sheets.
