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...
The separation of eddy current and hysteresis losses in transformer cores is obtained using the two-temperatures and the two-frequency methods. Loss calculations for six ratings using the voltage test waveform ratio are included to compare and analyze results. A brief description of the test methodologies, that are easy to apply, is given. An example of the application of the methodologies, the obtained...
