消除单片机控制晶闸管出现干扰的一种有效方法

A Method to Eliminate the Interference of Single-Chip Computer Controlling SCR

分析了单片机控制晶闸管存在的干扰因素和途径，指出了削弱和避免干扰所需满足的限制条件；提出了一种采用单片机８０Ｃ５５２控制晶闸管的电路结构和方法本方法已应用在某人工合成金刚石压机的加热系统中。

Analyses the causes and channels of the interference existing in the single-chip computer controlling SCR (Silicon Controlled Rectiticer),points out the necessary restrict condition to weaken or even eliminate the interference,puts forward a circuit structure and a programme of thyrister controlled by a 80C552 single-chip computer.The new method has been successfully used in the thermo-system of as ynthetic diamond roller,and the result is quite satisfactory.
