摘要
由于导通及开关损耗小以及易于使用等优点,IGBT在电力电子系统中得到越来越广泛的应用。在设计电路之前,需要精确的器件模型及模型参数对电路进行仿真。本文提出一种基于实验测量、仿真及优化算法的IGBT模型参数辨识方法。以BUP302为例,给出了静态参数及动态参数的结果。在参数辨识的基础上,文中还提出了模型参数有效性验证的方法,最后给出了有效性验证结果。
IGBT £Insulated Gate Bipolar Transistor is becoming more and more popular in many power applications, since it offers a good compromise between on-state loss, switching loss and easy of use. To develop circuits and systems using theses devices, model and model parameters are needed for use in circuit simulators. This paper presents a procedure for identifying the most important parameters to be used in IGBT models. As an example, the results of identified parameters of BUP302 arze given. Based on the identification, the paper presents the method for parameters validation. At last, the validation conclusion was given.
