基于有限元分析的直流偏置励磁铁芯损耗量化方法研究

Based on the finite-element analysis software Ansys Maxwell, this article proposed a simulation method for the core losses of pulsewidth modulation wave voltage excitation with dc bias which solves the problem of core losses calculation of magnetic components with different core structures in power converters. This article points out that the two key factors for core losses simulation are the magn...
