摘要: 脉冲形成网络常用于大功率固态调制器、微波驱动源以及激光激励源中,以便获取宽平顶的高压长脉冲输出。针对常用的雷利网络,根据宽平顶低纹波的应用需求,开展了优化设计技术研究,提出了基于单纯形优化法的设计算法。主要针对两种情形进行了优化设计及计算:一是电容值相等,通过优化电感值以获取最优的输出波形;二是约定电容值(电容值不完全相等),通过优化计算不同电容排列下的输出结果,寻求最优的电容排列组合及相应的优化电感值。上述优化算法结果表明,在两种情形下均可以获得较优的准方波脉冲输出,可以为准方波脉冲形成网络的工程实现提供一种新的方法。理论计算和电路仿真结果表明,所提出的方法合理可行。

Abstract: Pulse forming network (PFN) is often used in high-power solid-state modulator, microwave driver and laser exciter to obtain high voltage and long pulse output with wide flat-top. Aiming at the common used Rayleigh PFN with equal inductor and capacitor, according to the application requirement of wide flat-top and low ripple, the optimal design technology of PFN is studied, and the optimization algorithm based on simplex optimization method is proposed. The work is mainly carried out in two cases: first, the capacitance is uniform, and the optimal output performance is obtained by optimizing the inductance value; second, the capacitors are constrained, and through optimizing the inductance values under different capacitance arrangement, the optimal capacitance arrangement and the corresponding inductance value are worked out. The optimization results show that the quasi-square-wave pulse output can be obtained in both cases. A new method for design and engineering implementation of quasi-square-wave PFN can be provided. The theoretical calculation and circuit simulation results indicate that the proposed method is reasonable and practicable.-
