Abstract:
1. An inductor, comprising: at least one high permeability core gap piece positioned within a core of the inductor such that at least one magnetic flux path of the core of the inductor passes through the at least one high permeability core gap piece; wherein the at least one high permeability core gap piece has an effective magnetic permeability that is at least 1000 times greater than a permeability of air and varies so as to result in the at least one high permeability core gap piece is capable of affecting an inductance of the inductor based on, at least in part, on the effective magnetic permeability of the at least one high permeability core gap piece, wherein the effective magnetic permeability changes based, at least in part, on the following factors:
