摘　　要：为提高磁控电抗器(MCR)的快速性和准确性,设计了一种MCR快速响应电路,实现了MCR的快速励磁和快速去磁。在此基础上,利用数字信号处理器(DSP)芯片极强的运算能力和极高的稳定性,以及现场可编程门阵列(FPGA)芯片极强的控制性能,提出了一种以DSP和FPGA混合系统作为MCR控制系统的控制方案,该控制系统由信号取样、信号处理、信号输出、显示等模块组成。仿真和实验结果表明,该套系统可以对MCR进行准确可靠地控制,并使得MCR的励磁和去磁过程均在0.02 s以内完成,极大地提升了MCR的性能,拓展了MCR的应用范围。To improve the rapidity and accuracy of magnetically controlled reactors （MCRs）, we designed a fast response circuit for MCR which helps to realize both fast excitation and fast demagnetization of MCR. Then according to the strong capability and high stability of digital signal processors （DSP） and the excellent control performance of fieldprogrammable gate array （FPGA）, we proposed a control scheme for MCR which adopts a DSP/FPGA hybrid sys tem as its control system. The control system is composed of modules for different functions including signal sampling, signal processing, signal output, display, and so on. Further simulations and experiments of the system show that the sys tem could control MCR accurately and reliably, while ensuring both the excitation and demagnetization of MCR take less than 0.02 s, which is a great improvement in MCR performance that expands the application of MCR.
