Abstract
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.
