Modeling of Massive Inductors with the H-F Magnetodynamic Formulations via a Finite Element Technique ☆

Magnetodynamic problems are present everywhere in electrical systems in general and electrical equipments in particular. Thus, studying magnetodynamic problems becomes very important in the electromagnetic devices and is always topical subjects for researchers and designers in worldwide. The idea of this paper is to compute and simulate the distribution of local and global fields (magnetic flux density, magnetic field, eddy current, joule loss, current and voltage) in conducting and non-conducting regions. The H-Phi magnetodynamic formulations is proposed for massive inductors in order to link/couple with circuit equations defining currents or voltages. The method allows to solve problems in high frequency domains to take skin depths and skin effects into account.
