Transmission line simulation method based on wave process
-
摘要: 从波过程计算的角度，阐述了用传输线对脉冲形成网络进行模拟的原理和方法。该方法可以对元件参数随时间变化的脉冲形成网络，以及包含磁绝缘传输线、开关、内爆等离子体等的脉冲功率系统进行全电路模拟。与商业程序Pspice模拟结果比较表明：两种方法得到的电流、电压的峰值相对偏差不到5‰，在整个时间范围内，电流、电压的最大偏差均小于峰值的5%；两种方法得到波形几乎完全重合。在能保证准确度和收敛性的同时，该方法还具有直观、运算快速、易扩展等特点。Abstract: Principle and method to simulate pulse forming net(PFN) were expatiated from the viewpoint of wave process. The method can simulate PFN with temporal circuit parameters as well as pulsed power system with MITL, switch, implosion plasma. The high fidelity, quick convergence, straightforward procedure, rapid operation and the easy extension are characterized with wave process based method by comparison with Pspice simulation.
