Abstract
A high-leakage planar magnetic component such as an inductor, having a winding structure in which flat winding turns are oriented transverse to the plane of the winding structure, exhibits significantly lower winding losses than components having a stacked arrangement of flat winding turns parallel to the plane of the winding structure. A dense winding structure having such a transverse orientation can readily be made by forming a flat conductor into a coil using conventional wire winding techniques.
