基于电场诱导的反铁电相向铁电相转变中伴随有巨大电能量吸收的原理,实验研究了反铁电调节器对高压电脉冲的调节作用.工作电压是幅值为50kV、宽度为3.75μs的方型脉冲电压,反铁电调节器由锆锡钛酸铅反铁电陶瓷组成.实验结果显示,反铁电调节器消除了电脉冲前沿的上冲电压峰,填补了后沿的电压波谷,使电脉冲波形平滑化,从而达到了调节电脉冲波形的目的.测量得到的动态电滞回线结果表明,在上述电脉冲作用下材料发生了反铁电相与铁电相之间的转换.
Based on the principle of large electric energy absorption induced by the electric field induced antiferroelectric phase to ferroelectric phase, the regulation of high voltage electric pulse by the antiferroelectric regulator was experimentally studied.The operating voltage is 50kV with a width of 3.75 μs square pulse voltage, the anti-ferroelectric regulator made of lead zirconate titanate antiferroelectric ceramic.The experimental results show that the anti-ferroelectric regulator eliminates the surge pulse voltage front porch, to fill the voltage of the back porch Trough, so that the electrical pulse waveform smoothing, so as to achieve the purpose of adjusting the electrical pulse waveform.The measured dynamic hysteresis loop results show that the material under the action of the electrical pulse occurred between the antiferroelectric phase and the ferroelectric phase Conversion.
