Fabrication and Characteristics of Piezoelectric transformer using PMN-PZT
PMN-PZT 세라믹을 사용한 압전트랜스포머 제작과 특성
Abstract
In this paper, the voltage step-up ratio, efficiency and input impedance of the PMN-PZT cert- mic transformer(PT) were investigated for the variation of resonant frequency according to lead resistance. The output voltage and voltage step-up ratio are increased with the the increase of load resistance. The efficiency of PT showed the maxinum value of 91% at R
