Abstract :
A behavioral model of magnetic materials is presented. This model takes into account both hysteresis and dynamic phenomena. It predicts B(H), φ(t) and dφ(t)/dt characteristics, and a few pieces of experimental data are needed to identify its parameters. In this paper, the authors propose to validate the model for some typical applications encountered in power electronics. Results obtained are very satisfactory
