【Abstract】 Soft magnetic composites(SMCs) inherit the superior properties of soft ferrite and soft magnetic alloys, such as low eddy current and cost. SMCs meet the current development trend of high frequency and miniaturization. SMCs have been pay extensive attention by scholars and engineering developers in various countries. Measurement and simulation of magnetic properties of SMCs have become a hot spot in electrical engineering. Based on analysis of magnetic properties of, and research status of magnetic loss characteristics of SMCs, traditional calculation method and improved calculation method of magnetic loss were analyzed. The results could provide a theoretical basis for practical application of SMCs. It also lays a foundation for the simulation study of magnetic loss of SMCs.更多还原
