摘　　要：文章介绍了在PSM高压电源控制系统中,应用FPGA实现PSM模块步进时间间隔最小为1μs的精确定时。通过控制各个PSM模块的开通与关断,实现高压的输出与关闭。文章从硬件平台选择、控制逻辑设计、实验数据分析等方面着手,介绍了PSM电源脉冲控制器的设计与实现。实验表明:该脉冲控制器实时性良好,性能稳定可靠,满足PSM高压电源的控制需求。The article introduced the application of FPGA for completing 1 μs precise timing on step time interval of PSM module in the control system of PSM high voltage DC power supply. By controlling the turn - on and turn - off of the PSM module, on and off of high voltage can be realized. The article introduced the design and complement of pulse controller of the PSM power supply about the choice of hardware, design of control logic and analysis of experimental data. Experiment indicates that the controller has good capability of Real - time, stable, reliable operation, can meet the requirements of control system of the PSM high voltage power supply.
