Abstract

Solid-state dielectric materials have been widely investigated as potential candidates in compact pulsed power systems. In this paper, (Ba,Sr)TiO3 (BST) ceramic, with high relative permittivity and high voltage tolerance, was employed as the pulse modulation dielectric of the pulse forming line (PFL). Specifically, the electrode structure of the BST ceramic-based PFL was designed in Ω-shape, which can efficiently improve the voltage strength of the PFL and increase the output pulse duration. Pulse transmission and modulation performance of the PFL were analyzed numerically. Based on that, the PFL was developed and experimentally studied in our laboratory. With a charging voltage of 24 kV, square-shaped pulses with a peak voltage of 12 kV, and a duration of 141 ns, approximately, were obtained on a matched load of 3 Ω. Dimension of the BST ceramic-based PFL is 174 × 84 × 10 mm3. The energy density of the PFL can successfully reach 11.7 J/L, which meets potential applications including compact and solid-state pulsed power systems.

基于（Ba,Sr）TiO3陶瓷的低阻抗固态脉冲成形线研究。

固态介电材料作为紧凑脉冲电源系统的潜在候选材料已被广泛研究。本文采用具有高相对介电常数和高电压容限的（Ba,Sr）TiO3 （BST）陶瓷作为脉冲形成线（PFL）的脉冲调制介质。具体而言，在Ω-shape中设计了BST陶瓷基PFL的电极结构，可以有效地提高PFL的电压强度，增加输出脉冲持续时间。对PFL的脉冲传输和调制性能进行了数值分析。在此基础上，研制了PFL，并在实验室进行了实验研究。在充电电压为24 kV时，匹配负载为3 Ω，可获得峰值电压为12 kV、持续时间约为141 ns的方形脉冲。BST陶瓷基PFL的尺寸为174 × 84 × 10 mm3。PFL的能量密度可以达到11.7 J/L，满足紧凑和固态脉冲功率系统的潜在应用。
