| Abstract |
In this paper the inductance of square-shaped multilayer planar windings (MLPW) for power applications is investigated. Three well-known equations Wheeler's, Rosa's, and Monomial, which are suitable for single-layer (L1) planar windings, are extended to properly appertain to multilayer architectures. The proposed procedure is verified for two-layer (L2) windings, and the extension to three-layers (L3) or more is discussed, for different values of the geometric parameters. Furthermore, the dependance of thecoupling factor k with respect to the distance between the layers is investigated for L2. Finally, an experimental verification is carried out, for a number of selected windings. |
