| 摘 要： | 针对现有的三相移相触发芯片无法在较大噪声情况下工作,以及无法适应现有电网频率漂移的问题,提出了一种新型的SCR移相触发电路,具有改进的全数字去噪功能和适应电网频率漂移功能的设计方案。通过仿真和实际测试,该触发器能够躲开相对输入信号20%的噪声干扰,并且能在电网频率47 Hz～63 Hz的环境下工作,具有重要的工程应用价值。

| Abstract: | Aiming at the problems of unable to work with high input noise and frequency drift due to the unstable frequency of electricity network in existing three-phase phase trigger chip,this paper provides a new SCR phase-shift trigger circuit with an improved circuit to get rid of the noise and a function to adapt the frequency drift.By simulation and practical test,this trigger can avoid 20%input noise,and can work under frequency 47 Hz～63 Hz of the grid.The method is of great engineering value. |
