对 IGBT动态模型进行了详细的理论分析。由于 IGBT中含有宽基极、低增益的晶体管 ,因此采用双极性传输方程来描述 IGBT电流 ,以此作为模型的物理基础。用非准静态分析法描述 IGBT的动态电流、电压波形。并用MATL AB的模型语言—— S- Function实现动态仿真

Implement IGBT Dynamic Simulation Model by MATLAB Liao Jiaping Liu Jinnan Department of Science and Technology, HBPU; Wuhan 430068,China.Analyze dynamic simulation model of IGBT in detail. Because the structure of IGBT includes a wide base, low gain BJT, use a bipolar transport equation to describe the current of IGBT as the physics base. And use non quasi static method to analyze dynamic current and voltage. Implement IGBT dynamic simulation model by MATLAB.IGBT simulation model; bipolar transport equation; non quasi static; S Function simulation
