摘　　要：介绍了Pspice子模块的建立方法;根据气体开关和强流二极管的工作原理,建立了能够较为准确描述这些部件工作过程的子模块;模拟了"闪光二号"加速器二极管正常工作和短路状态下的电压电流输出结果,二极管电压电流和阻抗模拟结果与实验结果基本一致。建模方法和参数控制方法可以用于阻抗非线性、工作过程复杂、随机性较大的部件的电路模拟,有利于使用大规模相同部件电路的参数控制。The establishing method of Pspice subcircuit was introduced,and self-breakdown switch and high current diode subcircuits were created based on their principles of work,which can describe their working processes.The circuit of Flash Ⅱ accelerator was then built using the subcircuits created as its switches and diode.The simulation results of diode voltage,current and impedance in normal operation and short-circuit state accord with the experimental results.The method of subcircuit establishment and parameters control can be used to simulate the components with nonlinear impedance and complicated working process,and it is favorable for parameters control of circuits with a large number of identical components.
