Comparison of Potential Formulations for the Extraction of RL Parameters of Wound Inductor

Abstract

In this work, we highlight how the t-w magneto harmonic formulation can be used in case of multilayer wound inductor. This formulation has already shown its performances in case of multiply connected regions thanks to thick cuts made in the non-conducting domain allowing to impose net current in the conducting domain. Even though this technique is well known in electromagnetics community, it has not yet used in case of wound inductors consisting of several turns without circuit coupling.
