Abstract
Piezoelectric transformer(PZT) can be used advantageously in high output voltage power supply. Recently, it also can be used in AC/DC Converter for miniaturizing size nd lightening weight. The modeling of PZT was performed by the calculation method through the physical and electrical constants of the material. The attributes of PZT were derived by an approximate analysis for output voltage gain, and resonant frequency. The proposed method is verified by computer simulation and experiment.
