Discrete modelling of magnetic cores including hysteresis, eddy current and anomalous losses

A discrete dynamic model of a magnetic core including hysteresis, eddy current and anomalous losses is proposed. It is suitable for thin laminations and features a simple formulation and fast calculation. The calculations and measurements of an annular ring under different waveforms are presented. The model can be extended to include cores with thick laminations.< >
