Planar core with high magnetic volume utilization

摘要

A structure is disclosed, comprising: a first magnetic core portion comprising: a first plurality of leg posts that are to be surrounded by a first set of windings; and a first plurality of center portions that are not to be surrounded by windings; and a second magnetic core portion comprising: a second plurality of leg posts that are to be surrounded by a second set of windings; and a second plurality of center portions that are not to be surrounded by the second set of windings, wherein the first set of center portions and the second set of center portions are configured to provide a plurality of physically separate magnetic flux paths.

1. A structure comprising:
a first magnetic core portion comprising:
a first plurality of leg protrusions comprising a first protrusion that is to be surrounded by at least a first portion of a first winding, and a second protrusion that is to be surrounded by at least a first portion of a second winding; anda first plurality of center portions that are not to be surrounded by any windings; and a second magnetic core portion comprising:
a second plurality of leg protrusions comprising a third protrusion that is to be surrounded by at least a second portion of the first winding, and a fourth protrusion that is to be surrounded by at least a second portion of the second winding; anda second plurality of center portions that are not to be surrounded by any windings; wherein the first plurality of leg protrusions is different from the second plurality of leg protrusions; the first plurality of center portions and the second plurality of center portions are configured to provide a plurality of physically separate magnetic flux paths; a center portion among the first plurality of center portions is shorter than the first protrusion or the second protrusion; and a center portion among the second plurality of center portions is shorter than the third protrusion or the fourth protrusion.
