Abstract

An inductor array that includes a plurality of inductors where adjacent inductors share a core piece and thus a flux path to reduce the size and weight of the array. In one embodiment, the shared core pieces are formed as back-to-back U-shaped members defining an indented region at the center of the core piece. In another embodiment, a plurality of small block-shaped center core pieces in each inductor defines a plurality of gaps therebetween.
