Abstract

The fixed-point iteration method is widely used in electromagnetic field analysis involving hysteresis property due to its strong robustness, but it has the problem of low computational efficiency. In this paper, a modified fixed-point iteration algorithm is proposed where the convergence factor is adaptively adjusted for different time steps according to the variation of residuals, instead of being globally static in traditional ways. Numerical analysis for a C-shaped iron core characterized by inverse vector Preisach model is performed using the traditional method and the proposed method respectively. The efficiency, stability and applicability of both methods are assessed in which the proposed approach shows superior performance.
