摘要

摘要: 基于爆电换能原理，使用掺铌的PZT 95/5陶瓷组装换能器件，在垂直工作模式下，对爆电电源LRC电路响应进行了理论分析，并开展了脉冲大电流输出实验研究。实验采用多组PZT 95/5铁电陶瓷并联，利用平面波发生器作为冲击加载手段，获得了峰值5 kA以上的脉冲大电流，初始电流上升速率可达10~20 GA/s。实验结果与理论设计符合较好。

Abstract: The PZT 95/5 ferroelectric ceramics with niobium doped was assembled into the shock-activated energy transducer. Based on the explosive to electric energy transfer theory, the large pulse of electrical current output was investigated under the action of shock wave in normal mode, and the electrical response of LRC load was discussed, especially for the small resistance (R) and small inductance (L) load. Several shock wave tests were conducted, and the PZT 95/5 ceramic stacks in parallel were devised to generate large pulses of electrical current. The maximum output current reaches above 5 kA, and the rising rate of the initial current is to 10~20 GA/s. The experimental results accord very well with the calculations.
