摘要： A flux-channeled high current inductor (30) includes an inductor body (12, 14) having a first end and an opposite second end and a conductor (32, 34) 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 (50, 52, 54, 56) inducted by a current (36, 40) 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 (12) and a second ferromagnetic plate (14). The inductor may be formed from a single component magnetic core and have one or more slits (16) to define inductance. The inductor may be formed of a magnetic powder. A method is provided for manufacturing flux-channeled high current inductors.
