摘　　要：针对HL-2A装置极向场电源晶闸管触发器系统同步信号波形畸变严重、频率不断变化的特点,通过分析和比较各种滤波器的滤波效果,提出了一个多级数字滤波器联合滤波的方案。利用MATLAB软件搭建了该滤波器的仿真模型,并对其进行了仿真分析,理论上证明了该方案的可行性。通过估计算法的延时,证明了该数字滤波器满足实时信号处理的要求。To deal with the serious waveform distortion and frequency variation of the synchronous signal of the HL-2A poloidal field SCR power supplies, a multistage digital filter for thyristor trigger system is raised by analyzing and comparing the filtering effectiveness of each kind of filter. The simulation model of the filter is built using MATLAB and the feasibility of the method is proved through simulation analysis. By calculating the time delay, it is proved that the digital filter also satisfies real-time process.
