A Numerical Comparison between Preisach, J-A and D-D-D Hysteresis Models in Computational Electromagnetics

Abstract

The incorporation of hysteresis models in computational electromagnetic software is of paramount importance for the accurate prediction of the ferromagnetic devices’ performance. The Preisach and Jiles-Atherton (J-A) models are frequently used for this purpose. The former is more accurate and can represent a broad range of magnetic materials, but it is computationally expensive. The latter is more efficient but can accurately model only soft ferromagnetic materials. In this paper, a recently proposed hysteresis model, referred to as the D’Aloia-Di Francesco-De Santis (D-D-D) model, is shown to have the best trade-off between accuracy and computational burden. For the first time, a numerical comparison between the Preisach, J-A and D-D-D models is provided for a large class of hysteresis loops including soft, semi-hard and hard ferromagnetic materials.

Modeling Dynamic Hysteresis Curves in Amorphous Magnetic Ribbons

“…The value of the normalization constant K was equal to 0.0025 in this case. It is evident from the inspection of Figures 2 and 3 that hysteresis loops in quasi-static magnetization conditions for the considered core are regular and may be easily described, e.g., using the phenomenological description based on the arctangent function [31,32] or another convenient model [33,34]. However, in the present paper, we follow the approach outlined in [1] and take the experimentally determined H = H(B) curves as a reference in order to avoid additional errors inevitably introduced by the representations of quasi-static hysteresis curves.…”
