Abstract: A magnetic core structure for an electromagnetic component includes a first magnetic core piece having a planar section and a plurality of posts extending perpendicularly to and projecting from the planar section, and a second, L-shaped magnetic core piece assembled with the first piece and in abutting contact with the plurality of posts. The component also includes a plurality of windings respectively corresponding to each phase of a DC multi-phase power system. The component may be one of a transformer or inductor component and may be included in a DC/DC power converter application having high power density and improved efficiency.

Abstract: A low profile electromagnetic component assembly for a circuit board such as a power inductor includes a first shaped magnetic core piece comprising a bottom surface for seating upon the circuit board, a top surface opposing the bottom surface, and a groove defined on the top surface. A conductive coil winding includes first and second terminal sections and a center main winding section extending between the first and second terminal sections. The center main winding section comprises an elongated strip of conductor having a thickness oriented extend to perpendicular to a plane of the circuit board. The terminal sections define a different cross sectional area of conductor than in the center main winding section.
