摘　　要：由于IGBT是新型电力电子器件,通用仿真软件Pspice没有提供IGBT模型。本文以数理模型为基础,通过电路等效的方法模拟IGBT内部物理行为,建立了IGBT的Pspice模型。该模型能够精确模拟IGBT的静态和动态特性,且结构简单,参数易于提取,占据计算机资源较少。新模型的开关过程与Hefner数理模型开关过程进行仿真比较,可以看出新模型与较为精确的数理模型符合的较好,满足电路仿真精度要求。Since IGBT is a new power device,there is no IGBT model in Pspice.Based on physical-mathematical model,we use circuit equivalent method to simulate the physical behavior of IGBT and propose a new IGBT model in this paper,the model can simulate IGBT static and dynamic characters precisely,its structure is simple and characters can be extract easily and it can saves room in computer.Through comparing the switch wave of new model with Hefner physical-mathematical model,we can see the new model can satisfy precision request in circuit simulation.
