摘　　要：针对压电驱动微动平台开发了一种快响应动态电源。以FPGA内建DDS作为驱动电源控制器及信号发生器,基于集成高压运放设计了带补偿校正网络的桥式功率放大器,并进行了理论分析、仿真与实验研究。测试结果表明,该设计满足了精密定位系统稳定性、快速性及高精密的驱动要求。A fast-response dynamic power was designed to drive the piezo-driven micromotion stage.Constructing DDS based on FPGA as the controller and signal generator,a bridge-type power amplifier with compensation ＆ calibration network was designed based on integrated high-voltage op amp. By compensating and calibrating,stability margin is improved to meet the driving requirement of stability,rapidity and high precision.
