交流固态继电器及其在电机可逆运转中的应用

AC-SSR and Application in Invertible Motion of Motor

在简述固态继电器的分类与 ＡＣ－ＳＳＲ工作原理的基础上，介绍了ＡＣ－ＳＳＲ在单相和三相交流电动机正反转控制中的应用及应注意的问题。

On the base of briefly stating classification and property character of the Solid State Relay and working principle of the AC SSR. This paper introduces the application in positive and negative going motion control of the single-phase and three-phase AC motor and the problems must noticed.
