摘要大功率晶闸管以其高电压、大电流的特点在大容量系统中应用非常广泛。依据大功率晶闸管外特性利用Matlab/Simulink构建了一种晶闸管功能性子电路模型,并在建立的大功率谐振电路中进行动态仿真实验分析。仿真实验结果表明,该模型能够准确描述晶闸管的动态特性,弥补了Matlab工具箱中模型参数较少且难以准确描述晶闸管动态特性的不足。晶闸管功能性子电路模型实用性强,适用于大功率晶闸管电路的暂态分析。 High power thyristor has being used in high power systems widely for its high voltage and large cur- rent. A novel functional subcircuit model based on Matlab/Simulink according to the external characteristics of the device is proposed. Final test showed the transient process of thyristor in the simulation of a resonant circuit can be described accurately. The model remedy the deficiency in transient analysis of the Simulink model in toolbox. A good practicality of the proposed model for the transient analysis of high power systems has been ob- served.
