摘要
针对小型化紧凑型脉冲源的应用需求,开展了基于互耦电感的两节准方波脉冲形成网络设计技术研究。首先介绍了两节脉冲形成网络互耦电感解耦的条件,并根据常用的三种脉冲形成网络模型运用拉普拉斯变换推导出了相应的输出脉冲电流表达式,并利用准方波的Prony级数表达式,通过求解非线性方程组获得了准方波脉冲的解析表达式,进一步求解出各网络元件的参数。然后研究了电感耦合系数在电路中的影响,提出了利用互耦电感设计准方波脉冲形成网络的方法。模拟仿真结果表明:基于互耦电感的两节脉冲形成网络可获得输出波形质量较好的准方波脉冲输出。利用互耦电感这一巧妙设计,可以较方便地实现准方波脉冲形成网络的设计。
For the application demand of compact and miniaturized pulse source,the design technique of two-stage square pulse forming network(PFN)with mutual coupling inductors is developed.First,the decoupling conditions of this PFN are introduced.The corresponding output current expressions are derived using Laplace transform in the three commonly used network configurations.By using the Prony series expression of square pulse,the analytic expression is obtained by solving the nonlinear equations,and the parameters of each network element are worked out.The influence of the coupling inductors' coefficient in the circuit is studied.Then,the design method of two-stage PFN with mutual coupling inductors is proposed.The simulation results show that the output pulse with a certain width flat-top can be produced by using the designed PFN.With the ingenious design of mutual coupling inductors,the PFN producing square pulse can be conveniently realized.
