摘要
利用PCI-7464数据采集卡提供的DLL动态连接库函数及VB中的Timer控件，实现了8路0～10V的压电陶瓷驱动电源模拟控制信号的可编程输出，通过后续的放大电路，实现了0-300V控制电压的输出。所设计电源具有低纹波、多通道、高精度等特点，满足压电陶瓷的驱动要求。
The eight channels of 0-10 V programmable analog control voltage for PZT power were obtained through the DLL library for PCI-7464 data acquisition card and Timer control of VB. 0-300 V control voltage was output by the subsequent amplification circuit. The power supply has the features of low ripple, multi-channel, high-precision and meets the requirements for PZT driving.
