摘要
固态继电器是20世纪70年代新兴的电子元器件,由于它的无触点特性,使其在电气领域得到了日益广泛的应用。分析了交流固态继电器的结构与工作原理,阐述了固态继电器的特点,并介绍了几个交流固态继电器在自动控制系统中的应用实例。
The solid state relay （SSR） is the new developing electronic devices and components in the seventies of the 20th century. It had been used widely day by day in electric field for its contactless characteristic. The structure and principle of the AC solid state relay （AC - SSR） are analyzed. The characteristic of SSR is starecl, and several application examples of AC- SSR in automatic control system are introduced.
