The prediction of iron losses in magnetic steels submitted to alternating pulse voltages is studied and an efficient method is proposed. It is developed by coupling the pulse voltage form factor and the loss separation model. Prediction of iron losses becomes possible directly from the loss model corresponding to the sinusoidal flux density. This method is validated on silicon iron grain-oriented and non-oriented magnetic steels. The predetermined iron losses are coherent with those measured and this approach allows both simplicity and precision well appreciated by industry
