Abstract

Aiming at the shortcomings of traditional drivers by piezoelectric actuators in overheating

driving signal distortion and high speed requirements

this paper researches a driving method for a new motor based on the piezoelectric actuator. A driving circuit for the piezoelectric actuator based on a direct current step-up converter and a resonant circuit was proposed according to the circuit analysis of large capacitive load characteristic of a multilayer piezoelectric actuator. An offset circuit was presented to meet the demand of unbalanced voltage driving of the piezoelectric actuator. The Fourier method was used for the circuit wave analysis and power saving. Experiments show that the power consumption of the new driving circuit is 61.7% that of traditional linear drive circuits. It proved that the presented method is reliable for the drive of a new type of non-resonant piezoelectric motor. The experimental results indicate that the developed circuit could drive the motor smoothly with lower power losses

and the variable frequency and drive voltage have been realized.
