Simulation of Magnetic Circuits Including Hysteresis Nonlinearity
Magnetic circuits can be represented with a topological dual circuit. In the dual circuit, flux paths are modelled by hysteretic permeances instead of reluctances. Hysteresis effect is taken into account by using the Jiles-Atherton (JA) approach. In addition, iron losses due to eddy current are also included to the model. Comparison of simulated results with the experimental results from a core type transformer demonstrates the capability of the proposed method.
