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: An electromagnetic component for a circuit board includes first and second magnetic core pieces and a bifilar coil extending between the first and second magnetic core pieces. The bifilar coil includes a first coil segment having first and second surface mount terminations, and a second coil segment having third and fourth surface mount terminations. The bifilar coil and core pieces facilitate a significant height reduction in the component while offering the same performance as existing power inductor components.
