Abstract

The characteristics of a multilayer piezoelectric transformer were investigated using 0.05Pb(A $l_{0.5}$N $b_{0.5}$) $O_3$-0.95Pb(Z $r_{0.52}$ $Ti_{0.48}$) $O_3$+0.9wt%N $b_2$ $O_{5}$+0.5wt%Mn $O_2$+0.04wt% $V_2$ $O_{5}$ ceramics. The multilayer piezoelectric trans formers were developed for voltage step-up. The multilayer ceramic technology was applied in piezoelectric transformer. The electrical characteristics of the piezoelectric transformer (33x8.5x1mm) has the efficiency of above 85%, step-up ratio of 70 under the 130 kΩ load, and driving frequency of 93.5kHz, respectively.ctively.y.y.
