초록
In this study, multilayer piezoelectric transformer were manufactured using the PZN-PMN-PZT ceramic and then the electrical characteristics were investigated. The voltage step-up ratio of multilayer piezoelectric transformer showed the maximum value in the vicinity of 78.16kHz and increased according to the increase of load resistance. When the output impedance coincided with the load resistance, piezoelectric transformer showed the temperature increase of about
