Abstract
A flux-channeled high current inductor includes an inductor body having a first end and an opposite second end and a conductor extending through the inductor body. The conductor includes a plurality of separate channels through a cross-sectional area of the inductor body thereby directing magnetic flux inducted by a current flowing through the conductor into two or more cross-sectional areas and reducing flux density of a given single area. The inductor body may be formed of a first ferromagnetic plate and a second ferromagnetic plate. The inductor may be formed from a single component magnetic core and have one or more slits to define inductance. The inductor may be formed of a magnetic powder. A method is provided for manufacturing flux-channeled high current inductors.
