Abstract
Determination of parameters of anhysteretic magnetization curve plays the key role in modelling the characteristics of soft magnetic materials. This curve can be efficiently used to describe the characteristics of inductive components in SPICE or FEM modelling. Moreover, anhysteretic magnetization curve is the base of Jiles-Atherton model of magnetic hysteresis loop. Paper presents the method of identification of parameters of anhysteretic curves of soft magnetic materials without or with different types of anisotropy. Due to the fact, that calculation of anhysteretic curve of anisotropic materials requires numerical integration, optimization-based method is proposed. Moreover, open-source MATLAB/Octave scripts are provided to verify and validate proposed method for variety of anisotropic materials.
