Abstract:
1. A cooled high-power vehicle inductor, comprising an inductor core including a central axis; a first series of inductor windings around the central axis of the inductor core, the first series of inductor windings having an outer perimeter; a second series of inductor windings around the central axis of the inductor core, the second series of inductor windings having an inner perimeter that is substantially outside the outer perimeter of the first series of inductor windings, wherein the second series of inductor windings is electrically coupled to the first series of inductor windings; at least one heat transfer path disposed between the outer perimeter of the first series of inductor windings and the inner perimeter of the second series of inductor windings; an interface to an external cooling source; wherein the at least one heat transfer path comprises a first heat transfer insert made substantially from a thermally conductive material; and, wherein the first heat transfer insert is configured to transfer heat from the cooled high-power vehicle inductor to the external cooling source.
