摘　　要：介绍了将用在中国环流器2号 A(HL-2A)装置磁场电源系统中的晶闸管数字触发器,阐述了其工作原理。利用自适应预测技术克服了同步输入信号的频率变化和畸变对触发器性能的影响和干扰。In this paper, digital trigger which will be applied to the magnetic fields power supply in HL-2A tokamak is introduced. And the operating principle of it is analyzed. The characters of trigger are influenced and disturbed by the changing and aberration of frequency of a input of synchronous signals, but the question is solved by using the adaptive prediction technology.
