Method for making magnetic components with M-phase coupling, and related inductor structures

摘要

An M phase coupled inductor includes a magnetic core including a first end magnetic element, a second end magnetic element, and M legs disposed between and connecting the first and second end magnetic elements. M is an integer greater than one. The coupled inductor further includes M windings, where each winding has a substantially rectangular cross section. Each one of the M windings is at least partially wound about a respective leg.

1. A two-phase coupled inductor, comprising:
a magnetic core having opposing first and second ends and forming a passageway having depth and height, the depth being greater than the height, the passageway extending through the magnetic core in the depthwise direction from the first end of the magnetic core to the second end of the magnetic core; and first and second windings wound at least partially around a common leg of the magnetic core and through the passageway in the depthwise direction; the second winding being separated from the first winding by a linear separation distance throughout the passageway, the separation distance being along an axis perpendicular to an axis of the height of the passageway and perpendicular to an axis of the depth of the passageway, the separation distance being greater than the height of the passageway; the common leg of the magnetic core forming an outer surface of the magnetic core, the outer surface separating, in the depthwise direction, the first end of the magnetic core from the second end of the magnetic core.
