摘　　要：提出了一种基于进化差分(differential evolution,DE)算法的整流二极管高频建模方法.首先,通过矢量网络分析仪(vector network analyzer,VNA)提取了整流二极管截止时高频阻抗特性.然后,基于进化差分算法进行整流二极管高频特性建模,同时,对比了进化差分算法与遗传算法的拟合结果.结果表明:进化差分算法在拟合精度及运行速度均优于遗传算法.通过实测曲线与仿真曲线对比表明拟合效果良好,验证了模型及参数的准确性.最后,通过仿真验证了其导通关断特性.This paper proposes a high-frequency modeling method for the rectifier diode based on differential evolution(DE)algorithm.First of all,the vector network analyzer(VNA)is used to extract the high-frequency impedance charac-teristics of the rectifier diode on cut-off condition.Then,the high frequency characteristic modeling of rectifying diode is based on different evolution algorithm.At the same time,the fitting results of different evolution algorithm and genetic algorithm are compared with each other,and the results of different evolution algorithm are better than those of genetic algorithm algorithm both in fitting accuracy and running speed.Then,the comparison between the measured curve and the simulation curve shows that the fitting result is good,which verifies the accuracy of the model and parameters.Finally,the turn-on and turn-off characteristics of the rectifier diode are verified by simulation.
