Bond Graph Modeling of Current Diffusion in Magnetic Cores
Résumé
The paper presents different modeling approaches that yield a same bond graph representation structure. The first one is based on a variational approximation of the Magnetic Induction Diffusion Equation and supplies various degrees of modeling starting from the simple standard electrical inductor. The second approach is based on the diffusion representation and may be simply connected to numerical simulation of the Maxwell's Equations in Frequency Domain. Finally such approaches should be applied to advanced modeling of Integrated Power Systems that operate at high switching frequency.
