摘要
详细介绍了应用ＭＡＴＬＡＢ软件包建立ＩＧＢＴ仿真模型的机理和仿真模型的 工作原理。在建模过程中，利用ＭＡＡＩＢ软件包已有的理想开关模型，与一个非线性 电阻串联，该电阻具有ＩＧＢＴ输出特性相同的输出特性，建立起ＩＧＢＴ的仿真模型。对 建立起来的模型进行了静态与动态特性的仿真，得出了与实际技术参数非常吻合的仿 真结果。同时该模型结构具有强大的扩展性，在输入新的技术参数之后，可以圆满地仿 真其它种类的ＩＧＢＴ或功率开关元件。ＩＧＢＴ模型的建立，满足了开发新型电力电子电 路对建立新型电子元件仿真模型的要求，该模型在新型逆变焊接电源的研制过程中发 挥了重要的作用。
In this paper,the principle Of modeling Of IGBT by using MATLAB simulation software is intoduced in detail. IGBT model is built on an ideal switch block,which has been given in the MATLAB, and nonlinear resistor,which is in series with the ideal switch and has the same output characteristics with IGBT. The model is simulated in static and dynamic states,and the results obtained are in agreement with the data given by the date book. In addition,the struchture of the model has a powerful flexibility,and other kinds of IGBT or power switches can be simulated very well when their parameters are inputted into the model. The foundation of IGBT nmodel meets the needs for the simulation Of the new circuit, and the model Plays the important role in the developing new inverter resistance Welding machine.
