Abstract

A planar transformer assembly includes an insulative layer [111], a first spiral winding [12] thereon circumscribing a magnetic flux path [14], a second spiral winding [13] thereon in non-overlapping relation to the first spiral winding circumscribing the magnetic flux path, and a ferrite core assembly including first [18] and second [20] core sections defining a shallow gap or passage within which the spiral windings are disposed. In one embodiment, a plurality of laminated insulative layers are provided with a primary winding including a plurality of series-connected spiral subwindings [12-1,2---5] and a non-overlapping secondary winding formed on the various insulative layers. The non-overlapping structure and the order of the various windings minimize electric field gradients and thereby minimize electric field coupled noise currents.
