Aiming at demand for high-precision positioning of the beam director, a DC amplification type piezoelectric ceramic (PZT) driving power supply was designed to improve the driving characteristics of the PZT bimorph. D/A converter module convert the digital command signal occurring on the computer to the analog voltage signal, and the high-voltage linear amplifier module zoom the analog voltage signal in order to drive the PZT. The results show that the PZT driving power supply can be effectively used in the beam-directing device system, with the features of high output accuracy, fast response, strong driving ability, good stability, simple structure, high integration, and convenient debug.
