With the development of high-power microwave technology, the output power of the pulse generator is required more and more higher. In this paper, it is realized by increasing the output power of the module while the output impedance of the module changes little. The module of the generator is based on pulse forming network (PFN) and linear transformer (LT). Four Blumlein PFNs with arc-type configuration and 24 Ω characteristic impedance were connected symmetrically to the primary coil of the LTD and driven by two identical laser triggered spark switches to ensure four Blumlein PFNs synchronizing operation. On this basis, a two-stage high-power pulse generator based on PFN-LT is developed. The following technical parameters of the generator were achieved on a 12 Ω high-power solid resistor: output voltage amplitude of ∼250 kV and output power of ∼5.2 GW at a repetition rate of 5 Hz.

随着大功率微波技术的发展，对脉冲发生器输出功率的要求越来越高。本文通过在模块输出阻抗变化不大的情况下增加模块的输出功率来实现。发生器模块基于脉冲形成网络（PFN）和线性变压器（LT）。四个具有弧形配置和 24 Ω 特性阻抗的 Blumlein PFN 对称连接到 LTD 的初级线圈，并由两个相同的激光触发火花开关驱动，以确保四个 Blumlein PFN 同步操作。在此基础上，研制了一种基于PFN-LT的两级大功率脉冲发生器。发电机的以下技术参数是在 12 Ω 大功率固体电阻器上实现的：输出电压幅值 ∼250 kV 和输出功率 ∼5。
