Abstract
Multi-winding magnetic structures and methods of making multi-winding magnetic structures are disclosed. In one embodiment, a multi-winding magnetic structure includes a core constructed of a magnetic material and a plurality of windings. The core includes a core top, a core bottom, and a plurality of columns. The core top has an exterior edge defining a shape of the core top. A central section of the core top has a substantially constant thickness that defines a thickness of the core top. The core bottom is beneath the core top and has an exterior edge defining a shape of the core bottom. A central section of the core bottom has a substantially constant thickness that defines a thickness of the core bottom. The thickness of one of the core bottom and the core top decreases from an edge of its central section to its exterior edge. The plurality of columns extends from the core bottom to the core top and the plurality of windings are wound around the columns.
