Abstract
A core apparatus for a magnetic component includes first and second E-cores stacked with legs extending in the same direction. The first E-core includes a middle first core leg having a middle first core leg length, and the second E-core includes a middle second core leg having a middle second core leg length greater than the middle first core leg length such that a step is formed between the distal ends of the middle legs of the first and second E-cores. A third E-core may be positioned opposite the stacked first and second E-cores forming a stepped air gap between the middle first and second core legs and the middle third core leg.
