Abstract:
1. A core apparatus for a magnetic component, comprising: a first E-core having a first core thickness and including a second E-core having a second core thickness and including wherein the first and second E-cores are stacked against each other such that the middle first core leg and the middle second core leg extend in substantially the same direction; wherein a difference between the middle first core offset and the middle second core offset forms a stepped end profile at exposed ends of the middle first core leg and the middle second core leg; and a third E-core positioned opposite the stacked first and second E-cores, the third E-core being a single non-stacked core and including a first outer third core leg, a second outer third core leg, and a middle third core leg, the middle third core leg having a constant middle third core leg length extending toward the stacked middle first and second core legs, the middle third core leg being shorter than the first and second outer third core legs by a middle third core leg offset, the middle third core leg offset being less than the middle second core offset, the third E-core having a third core thickness substantially equal to the sum of first and second core thicknesses.
