Implementation of hysteresis model in transient analysis of nonlinear reluctance networks

This paper introduces a method for implementation of hysteresis models in nonlinear reluctance networks for performing transient analyses. The proposed method for solving the nonlinear circuits is based on local linearization and doesn´t have the problems of non-convergency and demands to high number of iteration. The ability of coupling between electrical and magnetic circuit make it very suitable for study transient phenomena in a power network related to nonlinearity of magnetic materials such as ferroresonance, inrush current and DC magnetization.
