Abstract:
1. A coupled inductor having length and width, the coupled inductor comprising: a ladder magnetic core including at least two rails extending in the lengthwise direction and a plurality of rungs, each of the plurality of rungs connecting the at least two rails in the widthwise direction; and a single-turn winding wound around each of the plurality of rungs such that (1) the winding includes three rectangular sections facing the rung and (2) opposing ends of the winding form respective solder tabs partially under the rung and extending away from the rung in the widthwise direction; each single-turn winding having width and thickness along its respective rung, the thickness of the winding being orthogonal to an inner surface of the winding facing the rung, and the width of the winding being greater than the thickness of the winding.
