摘要
介绍了HL-2A上基于脉冲步进阶梯调制(PSM)技术的高压电源控制系统的研究。控制系统以数字信号处理+现场可编程门阵列(DSP+FPGA)为架构,控制112个每秒采样(SPS)模块,按照一定的控制方式使电源输出稳定的电压。DSP负责数据传输、通讯、控制算法等;FPGA利用其强大的逻辑功能输出所需的脉冲。通过对程序的编写、仿真和调试,实验结果表明该控制系统的特性达到了设计要求。
The research of high voltage power supply control system on HL-2 A tokamak based on the pulse step modulation technology was introduced. Based on the digital signal processing technology and the field programmable gate array technology(DSP & FPGA), the control system controls 112 SPS(sample per second)modules and outputs the stable voltage according to certain control mode. DSP is responsible for data transmission, communication and control algorithms, and so on, and FPGA uses its powerful logic function to output the desired pulse. Through the programming, simulation and debugging of the program, the experimental results show that the characteristics of the control system meet the design requirements.
