Abstract
An extension to the Steinmetz equation is proposed, to enable estimation of hysteresis losses in magnetic core materials with nonsinusoidal flux waveforms. The new formulation is shown to avoid anomalies present in previous modified-Steinmetz-equation calculations of loss with nonsinusoidal waveforms. Comparison with experimental measurements in MnZn ferrite shows improved accuracy. The result may be optionally formulated in terms of an effective frequency and an effective amplitude, and options for defining these are discussed.Keywords
