A modified analytical method for core losses calculation in magnetic laminations for a wide range of frequency and flux density

In this paper, a modified analytical method, based on Maxwell's equations is developed to calculate core losses for a wide range of magnetic flux density and frequency. In this method average permeability from experiments and some available material's features are used to calculate both hysteresis and eddy current losses analytically. This method takes the skin effect into account and the real value of permeability, is defined to improve the method accuracy. The main advantage of this method is its simplicity and accuracy especially for higher values of frequency and magnetic flux density in comparison with the other methods. Finally the simulation results are verified by experimental results.
