【摘要】 玻璃陶瓷因具有高介电常数和高体击穿场强,作为高密度储能介质在紧凑型固态脉冲功率系统中有着非常好的应用前景。文中研究了以玻璃陶瓷制备的不同电极宽度或介质厚度的固态脉冲形成线的传输特性。实验采用了带状线的单传输线结构和火花隙开关,考虑到回路分布参数的影响,通过测量失配状态下传输线短脉冲输出波形的脉宽、幅值、反射波幅值,得到了电极宽度W与极板间距d之比W/d在0.6至3.5范围内的固态线特性阻抗,实验结果在该范围内与经验公式相符。更多还原

【Abstract】 With high permittivity and high bulk breakdown field strength,Glass-ceramic has good foreground in compact solid-state pulsed power systems as a high stored energy density material.Transmission character of B₂O₃ glass-ceramic solid-state pulse forming line with different electrode width or separation distance is researched.In consideration of the effect of circuit distribution parameters,characteristic impedance is calculated through pulse width,amplitude and reflected wave amplitude of short output waveforms from the experiments with unmatched load.The measured characteristic impedances of lines with the ratio of electrode width and separation distance from 0.6to 3.5 correspond to experience formula.更多还原
