Abstract
This study investigates the voltage amplification function characteristics of a piezoelectric transformer. The impedance curve and equivalent circuit parameters of PTs were measured using an impedance analyzer, and an automatic measurement system based on NI-LabVIEW was established to measure the step-up ratio. OrCAD PSpice software was used to analyze the load characteristics of the PT. This study analyzed the relationship between the step-up ratio and resonance frequency and that between the step-up ratio and the load. Finally, a motor driver must be designed such that the PT can effectively output a high voltage to drive the ultrasonic motor.
