Abstract
A coupled inductor includes a ladder magnetic core including two opposing rails extending in a lengthwise direction and joined by a plurality of rungs. The coupled inductor further includes a respective winding wound around each of the plurality of rungs. The plurality of rungs are divided into at least two groups of rungs, and a lengthwise separation distance between adjacent rungs in each group of rungs is less than a lengthwise separation distance between adjacent rungs of different groups of rungs.
