Abstract

In this study, in order to develop high power piezoelectric transformer, we compared the piezoelectric transformers dimension. The basic composition of piezoelectric ceramics is ternary $0.01Pb(Ni_{1/3}Nb_{2/3})O_3-0.08Pb(Mn_{1/3}Nb_{2/3})O_3-0.91Pb(Zr_{0.505}Ti_{0.495})O_3$. The voltage step up ratio of piezoelectric transformer showed the maximum value at the near of 81 kHz and increased according to the increase of load resistance.
