Abstract

An inductor that includes end core pieces and a plurality of center block core pieces between the end core pieces that define a plurality of gaps. The end core pieces are made of an amorphous alloy to provide good magnetic field properties and the center core pieces are stamped magnetic sheets forming a laminate structure to provide ease of manufacturability. In one non-limiting embodiment, the end core pieces are an amorphous iron alloy and the center core pieces are stamped silicon-iron.
