“…This approach is similar to litz wire where individually insulated strands are twisted or woven together to cancel much of the flux that causes proximity-effect loss. Similar effects in parallel layers have also been studied in planar transformers [8], [9].…”

This work investigates the performance of multilayer foil windings in which the layers are interchanged to balance the flux linked by each layer and thus the current is shared equally between layers. Prototype transformers were built to confirm how much of the theoretical loss reduction is achievable in practice. The accuracy of the method to determine the location of the interchange is improved by considering individual turn lengths. In addition, the method is extended to any number of layers and several winding configurations. A discussion of the construction and termination of these windings is included as they greatly affect a component's performance.

“…To this purpose, a simplified version of the harmonic model presented in [35] is developped in this paper. The approach is quite similar to the method proposed by Weichen in [36], but much easier to implement. It is based on a well-known physical principle called "principle of least action".…”

“…In addition, windings of planar transformers are piled up by copper foil in PCBs, which makes skin effects, parasitic parameters controllable. As a result, planar transformer has the advantages of higher current density, high efficiency, lower leakage inductance, small volume and wider bandwidth [1]. Besides, the repeatability of planar transformers is much better than conventional transformers because of the possibility of mass production of PCBs.…”
