摘　　要：针对含铁芯电感器的非线性问题，基于磁路基本原理，利用磁路计算及有限元分析方法，从理论上分析非线性电感器电感量与励磁电流的关系。并通过在ANSOFT／MAXWELL中建立的铁芯电感器有限元分析模型，分析其非线性特性，实验结果与仿真分析相吻合，为相应系统模型的建立提供了一定的理论基础。With the use of magnetic circuit calculation and finite element analysis method based on magnetic circuit basic principle, the relationship between the inductance and excitation current in the purpose Of solving the nonlinear problems of inductor with iron core is analyzed. Then by using ANSOFT/MAXWELL software, a FEM can be established to analyze the nonlinear properties. Finally,it can be proved that the experimental results can coincide with the simulation analysis and also provides some theoretical basis for the establishment of syste/n modeling.
