Abstract :
This paper shows that the common methods of loss calculation for ferro- and ferrimagnetic materials fail in the case of nonsinusoidal magnetic fields and DC premagnetization appearing in new power converter topologies. For this reason a new dynamic calculation model based on the static Jiles-Atherton model of ferromagnetic hysteresis is presented. A good accordance between calculations of the dynamic model and experimental results is shown for any dynamic field condition
