SPICE-compatible high frequency physical modeling approach for an inductor

Multi-physics modeling in power electronics contains EMC studies, thus conception requires modeling of passive elements. These models need to be compatible with the simulation software usually used in the industry. An analysis for modeling an inductor at high-frequency is presented in this study. The method takes into account the proper inductances of the turns, the mutual inductances between them, the parasitic capacitances, and the resistance of the windings. The originality of the model is that it is based on physical geometries and the material characteristics of the inductor and covers a large frequency bandwidth. These elements are used to create an analytical model based on electrical equations in order to provide the frequency dependent impedance of the inductor. The model is validated using experimental measurements.
