Abstract
For reducing volume requirements and magnetic flux leakage, a compact inductor includes a first planar core with a first core thickness along a first axis orthogonal to a plane of the first planar core. In addition, the inductor includes a second planar core disposed parallel to the first planar core with a second core thickness along the first axis. The inductor further includes a plurality of electrical windings disposed between and adjacent to an inside plane of the first planar core and an inside plane of the second planar core. The electrical windings may include insulated electrical wires. No magnetic teeth may be disposed between the first planar core and the second planar core. The first axis is parallel to a magnetic axis of each electrical winding.
