| 摘 要： | 本文对用微型计算机取代传统的可控硅驱动控制装置作了初步的探讨。共原理为将系统调节信号经定时器转换为移相脉冲串去触发可控硅进行三相全控整流。此项设计方案大大开拓了微型机的应用范围,在工业控制和新产品开发中具有广阔的前景。

| Abstract: | Using a microcomputer in the wind tunnel instead of con-ventional SCR drive controlling equipment has been studed in this paper.The principle is that the system adjustment signals are changed into shift-pulses via a timer so as to trigger SCR for three-phases full-controlrectification.The idea of the design has widely extended the range of themicrocomputer applications. It will have broadects prospects in industrialcontrol and new products exploring in the future. |
