Effective properties and eddy current losses of soft magnetic composites

This paper presents a semi-analytical homogenization model for Soft Magnetic Composites (SMCs), providing the effective magnetic behavior and level of Eddy Current (EC) losses. Both linear nonlinear are considered. A circuit made SMC is then modeled with Finite Element Model (FEM). The size heterogeneities being much smaller than device size, proposed approach relieves burden very fine mesh in FEM, by using properties an equivalent homogeneous material. validated comparing results on homogenized ones obtained from computationally heavy FEM describing mesh. show that provides accurate description EC losses both cases.
