Abstract
A matrix integrated magnetics (MIM) “Extended E” core in which a plurality of outer legs are disposed on a base and separated along a first outer edge to define windows therebetween. A center leg is disposed on the top region of the base and separated from the outer legs to define a center window. The center leg is suitably positioned along a second outer edge opposite the first or between outer legs positioned along opposing outer edges. A plate is disposed on the outer legs opposite the base.
Claims20
A matrix integrated magnetic (MIM) core, comprising:
- a base having first and second outer edges separated by a top region;
- a plurality of outer legs on said top region of said base along said first outer edge;
- and
- a center leg on said top region of said base along said second outer edge that spans said plurality of outer legs and separated therefrom to define a center window adjacent said plurality of outer legs and said center leg.
A method of forming a matrix integrated magnetic (MIM) core, comprising:
- forming a base having first and second outer edges separated by a top region;
- forming a plurality of outer legs on said top region of said base along said first outer edge;
- and
- forming a center leg on said top region of said base along said second outer edge that spans said plurality of outer legs and separated therefrom to define a center window adjacent said plurality of outer legs and said center leg.
A power converter, comprising:
- a first current doubler rectifier, including:
- at least one switch coupled to an input of said power converter, and
- a first matrix integrated magnetic (MIM) core, coupled to said at least one switch, including:
- a base having first and second outer edges separated by a top region,
- a plurality of outer legs on said top region of said base along said first outer edge, and
- a center leg on said top region of said base along said second outer edge that spans said plurality of outer legs and separated therefrom to define a center window adjacent said plurality of outer legs and said center leg;
- and
- a second current doubler rectifier, including:
- at least one switch coupled to said input of said power converter, and
- a second matrix integrated magnetic (MIM) core, coupled to said at least one switch, including:
- a base having first and second outer edges separated by a top region,
- a plurality of outer legs on said top region of said base along said first outer edge, and
- a center leg on said top region of said base along said second outer edge that spans said plurality of outer legs and separated therefrom to define a center window adjacent said plurality of outer legs and said center leg.
