摘要

基于陶瓷的脉冲形成线（PFL）是一种固态器件，在紧凑型脉冲功率系统中有着广泛的应用。本文对陶瓷基 PFL 的特性阻抗进行了理论分析，并提出了一种基于阻抗匹配电极的改进型 PFL。改进后的 PFL 有效提高了平顶比，缩短了上升和下降时间，增强了其潜在的适用性。使用改进型 PFL 进行的实验表明，在 33 kV 充电电压和阻抗匹配负载条件下，输出脉冲宽度可达 86 ns，匹配阻抗为 3.9 Ω。改进型 PFL 输出波形的平顶比达到 72%，而典型 PFL 为 49.5%，并且上升和下降时间更短。

Investigation of an improved ceramic-based pulse-forming line based on impedance matching electrode.

A ceramic-based pulse-forming line (PFL) is a solid-state device with a wide range of applications in compact pulsed power systems. In this paper, the characteristic impedance of a ceramic-based PFL is theoretically analyzed, and an improved PFL based on an impedance matching electrode is proposed. The improved PFL effectively increases the flat-top ratio and reduces the rise and fall times, enhancing its potential applicability. Experiments using the improved PFL show that, under a charging voltage of 33 kV and with an impedance matching load, the output pulse width can reach 86 ns with a matching impedance of 3.9 Ω. The improved PFL output waveform has a flat-top ratio that reaches 72%, compared with 49.5% in a typical PFL, and exhibits shorter rise and fall times.
