Compact power inductor

Abstract

A closed ferromagnetic housing has a pair of access ports and a center ferromagnetic post extending from and between opposite ends thereof. At least one conductor, contained within and completely surrounded by the closed ferromagnetic housing, is wound around the center ferromagnetic post such that the closed ferromagnetic housing, center ferromagnetic post, and at least one conductor form an inductor in which the ferromagnetic housing and the center ferromagnetic post define a core of the inductor and the at least one conductor defines a coil of the inductor. The access ports are configured to permit flow of coolant into the closed ferromagnetic housing and around the center ferromagnetic post to cool the at least one conductor.
