软磁铁氧体环形磁芯磁损耗时域宏观磁学建模方法

This article presents a new modeling approach capable of predicting Eddy current losses in soft ferrite cores as a function of the winding current. The proposed model is formulated in the time domain, which defines the magnetic core as a repeated regular structure of magnetic material grains and grain boundary in space. In this way, the homogenization process of the material is avoided, which is i...
