摘　　要：共模电感,是设计用来过滤开关电源中共模电磁干扰信号的电感器。本文先通过对共模电感二阶电路模型的建立,再对影响共模电感阻抗的各个因素逐个进行解析,并给出阻抗的计算公式,从而为磁元器件工程师提供一种定量分析共模电感阻抗的方法。Common mode inductors are inductors which designed to filter Common mode interferenee signal in SMPS.Through the establishment of the RLC circuit model of the common-mode inductor,this paper analyzes the various factors affecting the impedance of the common-mode inductor one by one,and gives the calculation formula of the impedance,providing a method for the magnetic component engineer to analyze the impedanee of the common-mode inductor.
