International Classification:

H01F 27/24
H01F 27/28
H02M 3/04

Abstract:

In some examples, a patterned magnetic core includes a first sub-score and at least one second sub-core. The first and second sub-cores are spaced apart by a gap, optionally filled with material of sufficiently low electrical conductivity. Each of the first and second sub-scores includes a number of magnetic layers and a number of interlamination layers disposed between the magnetic layers in an alternating fashion.

H01F 17/04

Abstract:

The subject matter described herein relates to laminated magnetic cores, methods of fabricating laminated magnetic cores, and electric devices using laminated magnetic cores. In some examples, a method for fabricating a laminated magnetic core includes depositing a first magnetic layer and depositing an interlamination layer of over the first magnetic layer. The interlamination layer comprises a partially conducting material having a conductivity greater than or equal to 10S/cm and less than or equal to 10S/cm. The method includes depositing a second magnetic layer over the interlamination layer. The method can include sequentially depositing additional interlamination layers and additional magnetic layers in an alternating fashion to produce the laminated magnetic core.
