Abstract
A multiple phase inductor includes a magnetic core having two end pieces and a plurality of legs extending between the end pieces to form flux paths which pass through the end pieces and the legs. Each leg includes a stack of "I" shaped laminations which are positioned between the end pieces to form two gaps in at least one of the flux paths. A coil is wound around each of the legs and all of the coils present substantially the same inductance to an external power circuit. By providing two gaps in each of the legs, localized heating of the turns of the coils is reduced.
