| Abstract: | In this paper,the numerical computation method for magnetic field and iron loss of electromagnetic systems excited by AC&DC supplies is proposed.The B-H curves and W-B m curves of iron core material under AC&DC magnetization are measured with the help of a double Epstein Frame.The verification example shows its validity and correctness. |
