Accounting for dynamic losses in the Jiles-Atherton model of magnetic hysteresis

Abstract

When designing semiconductor pulse converters of power systems operating in peak load conditions, it is necessary to calculate their characteristics and parameters, taking into account the magnetization reversal processes in the magnetic circuits of transformers and chokes. Magnetic materials of magnetic cores exhibit nonlinear, hysteretic, and dynamic properties due to the presence of classical vortex and additional losses. Various dynamic models, based on the classical Jiles–Atherton (JA) approach, are presented in the literature, however, they are unstable for textured materials and cannot be explained from a physical point of view. These models show certain non-physical situations expressed by the deformation of the hysteresis loop in the saturation region. In this paper, the direct and inverse dynamic hysteresis models are presented, based on the application of the theory of field separation. This approach explains some of the energy aspects of the JA model.
