摘要
准确的模型及模型参数是安全、合理使用电力电子器件的保证。本文采用了一种基于实验和仿真的电力电子器件模型参数辨识方法,通过优化算法,使仿真波形逐步向实验波形逼近,以达到参数辨识的目的,并在此基础上,对所辨识的参数进行了有效性验证。文中以PIN功率二极管BYT120-100为例,给出了模型参数辨识及有效性验证结果,并进一步论述了IGBT模型参数辨识及其有效性验证的基本思路。
Accurate model and model parameters are the pledge to use power electronic devices safely and reasonably.This paper describes method for identification and validation of model parameters for power electronic devices based on simulation and experiment.By optimizing,simulation wave approaches experimental wave,and the parameters are identified.Based on the identification,the parameters are validated.As an example, the results of identification and validation for PIN diode BYT120-100 are presented.The basic roadmap for the identification and validation for IGBT are given.
