摘要
压电驱动方式因具有位移分辨率、机械耐久性及速度高,输出力大,功耗低和频带宽等优势,因而被广泛采用。文章总结并分析了压电驱动的驱动要求与驱动方式,将压电驱动电路划分为直流升压转换模块、直流电压校准模块、开关放大器驱动模块、交流电压校准模块及控制模块,提出了一种结构简单、输出稳定以及可小型化的双级压电驱动电路系统,完成了将5V低压直流电转换为280V的高压交流电的设计目标,可以自由地改变输出方波信号和正弦信号的幅值、频率和占空比,并对压电驱动电路的带载能力、输出功率和效率作了分析。
The piezoelectric drive method is widely used since it has the outstanding advantages of high mechanical durability,speed and great output strength,low power consumption as well as wide bandwidth.The drive requirements and ways of the piezoelectric drive are analyzed in the paper.The piezoelectric drive circuit is divided into DC boost converter module, DC voltage calibration module,switch amplifier drive module,AC voltage calibration module and control module in this paper.A two stage piezoelectric drive circuit system with simple structure,stable output and miniaturization is proposed.The design goal of converting the low voltage DC of 5 V into high voltage AC of 280 V has completed,and the amplitude, frequency and duty ratio of the square wave signal and sine wave signal can be changed freely.The load carrying capacity,output power and efficiency of the piezoelectric drive circuit are also analyzed in the paper.
