Dynamic Bridge Piezoelectric Amplifiers with Signal Generator

Abstract:

Piezoelectric amplifier is a very important part of the piezoelectric actuator. Not only positioning accuracy, but also dynamic performance and power are demanded more and more highly. At present piezoelectric amplifier are mainly used in static applications, power and frequency response are usually incompatible. This paper developed a new type of piezoelectric amplifier to meet high demand for dynamic, which takes dual-power supply, bridge-output to achieved slew rate, power were doubled, and maintain a wide frequency range at the same time. Controller implements DDS unit through FPGA, which could achieve sine, triangle, square and sawtooth.
