Planar core with high magnetic volume utilization

Abstract

A disclosed method comprises: specifying a WaAc product of a first transformer having a three-legged core; determining a window area Wa of the first transformer; determining parameters of the first transformer, including a core area Ac, a height of c, and a width of b; specifying, based at least in part on the parameters of the first transformer, a second transformer having the WaAc product, the window area Wa, and the core area Ac and comprising: a first magnetic portion comprising: a first plurality of leg posts that is to be surrounded by a first set of windings; and a first plurality of center portions that is not to be surrounded by windings; and a second magnetic core portion comprising: a second plurality of leg posts that is to be surrounded by a second set of windings; and a second plurality of center portions that do not receive windings.
