Modelling static and dynamic hysteresis in time domain reluctance networks

This paper introduces a novel method for taking into account the losses of magnetic materials in a time domain reluctance network analysis. The reluctance network method is a fast and practical method of electromagnetic analysis of magnetic devices. However, in conventional methods only non-linear properties of magnetic materials are considered. The method presented in this work improves the reluctance network method to manage both static hysteresis and dynamic eddy currents in the time domain. It can be used for calculation of losses and consider their effects in transient studies. The accuracy and efficiency of the method is confirmed by experiment.
