摘要
A homogenized model based on the Pry and Bean model is generalized to represent the ac hysteretic characteristics of an actual grain-oriented silicon steel sheet. A parameter for the frequency dependence of eddy-current loss is introduced. The generalized model improves the evaluation accuracy of eddy-current loss and the representation of ac B-H loops under the condition of a sinusoidal magnetic flux. The generalized model also accurately represents ac B-H loops having minor loops.
