Extended E matrix integrated magnetics (MIM) core
View Patent ↗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.
1. 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 top of said base along two opposite edges of said base defining windows therebetween;
a center leg on said top region of said base disposed along a center of said base between said outer legs, separated from and spanning said outer legs to define two center windows; and
a plate opposite said base that covers said outer legs and windows therebetween, said center leg and said center windows.
2. The MIM core of claim 1 , wherein said plurality of outer legs exceeds two.
3. The MIM core of claim 1 , wherein said plurality of outer legs are disposed parallel to each other and perpendicular to said center leg.
4. The MIM core of claim 1 , wherein a width of said center windows is constant between said center leg and each of said plurality of outer legs.
5. The MIM core of claim 1 , wherein said base is rectangular.
6. The MIM core of claim 1 , wherein ones of said plurality of outer legs have a winding coupled thereto.
7. The MIM core of claim 1 , wherein said plurality of outer legs have primary and second windings coupled thereto.
8. The MIM core of claim 1 , wherein said center leg has a winding coupled thereto.
9. The MIM core of claim 1 , wherein said center leg is one piece.
10. The MIM core of claim 1 , wherein said center leg is shorter than said plurality of outer legs and forms an air gap between said center leg and said plate.
11. 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 top of said base along two opposite edges of said base defining windows therebetween;
forming a center leg on said top region of said base disposed along a center of said base between said outer legs, separated from and spanning said outer legs to define two center windows; and
placing a plate opposite said base that covers said outer legs and windows therebetween, said center leg and said center windows.
12. The method of claim 11 , wherein said plurality of outer legs exceeds two.
13. The method of claim 11 , wherein said plurality of outer legs are disposed parallel to each other and perpendicular to said center leg.
14. The method of claim 11 , wherein a width of said center windows is constant between said center leg and each of said plurality of outer legs.
15. The method of claim 11 , wherein said base is rectangular.
16. The method of claim 11 , wherein ones of said plurality of outer legs have a winding coupled thereto.
17. The method of claim 11 , wherein said plurality of outer legs have primary and second windings coupled thereto.
18. The method of claim 11 , wherein said center leg has a winding coupled thereto.
19. The method of claim 11 , wherein said center leg is one piece.
20. The method of claim 11 , wherein said center leg is shorter than said plurality of outer legs and forms an air gap between said center leg and said plate.
