摘要
简要讨论了压电变压器的工作原理和结构及压电材料的选择。报道了铌镁锰锆钛酸铅（ＰＭＭＮ－２）四元系压电陶瓷材料的研制概况，设计并制作了一种带宽窄、升压比和转换效率高的ＥＴ型压电陶瓷变压器。通过有关单位试用性试验，能达到引爆要求。
This paper gives a brief discussion to the principles and structure of piezoelctrictransformer and to the choice of piezoelctric materials.The ET-type piezoelectric ceramic transformer ofnarrow band ,high voltage stepup ratio and high transforming efficiency is fabricated by use of the self-developed PMMN -2 piezoelectric ceramics.The new transformer has passed through the highvoltage igniting experiment given by the unit concerned.
