摘　　要：针对光束定向器的高精度定位需求,以提高压电陶瓷双晶片的驱动特性为目的,设计一种直流放大式的压电陶瓷驱动电源,通过D/A转换模块把计算机发出的数字指令信号转换为模拟电压信号,通过高压线性放大模块把模拟电压信号进行高压放大驱动压电陶瓷。结果表明:该驱动电源具有输出精度高、响应速度快、驱动能力强、稳定性能好、结构简单、集成度高、调试方便等特点,能有效地应用于光束定向器驱动系统中。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.
