AbstractThis paper presents a dynamic equivalent circuit model of solid magnetic cores for high frequency operation in power electronic circuits. The effects of eddy current, domain wall motion and hysteresis are taken into account by distributed equivalent resistor and distributed non-ideal differential inductors, respectively. The Preisach hysteresis model is employed to simulate hysteresis effects in the inductors. A recently developed discrete transform technique based on the transmission line method is adopted to discretize the model for numerical dynamical analysis. The resultant model is just a tridiagonal system of equations. The theory is verified by experiments. The proposed model can be easily incorporated into existing simulation packages.
