摘要

In this study, a low temperature sintering thickness-vibration-mode multilayer piezoelectric transformer for a DC-DC converter was manufactured using (Pb_(0.76)Ca_(0.23)Sr_(0.01))Ti_(0.96)(Mn_(1/3)Sb_(2/3))_(0.04)O_3 ceramics. Its electrical properties were investigated according to the variations in frequency and load resistance. The voltage step-up ratio of the multilayer piezoelectric transformer showed a maximum value at a resonant frequency of 1.444 MHz and increased with an increase in load resistance. The efficiency of the multilayer piezoelectric transformer showed the highest value at a load resistance of 17 Ω. The output power increased with increasing input voltage. When the output impedance of the multilayer piezoelectric transformer coincided with the load resistance, output power showed the highest value of 18 W within a 20 ℃ temperature increase.
