摘　　要：针对目前市场上固态继电器的特点,分析和应用过零触发脉冲控制理论,结合单片机技术开发了一种功能强、精度高的嵌入式功率调节器.微控制器从整流输出端取得电压信号,经过内部程序判断,输出PWM波控制双向可控硅的通断比进行功率调节,其中调节参数可由按键修改,并保存在E2PROM内.本设计还可以适用于其他多种固态继电器,只需变换固态继电器,载入不同的程序,即可实现不同的触发方式、不同电流范围的控制.According to the characteristics of solid-state relays in current market,this paper analyzes and applies the theory of zero-crossing trigger pulse control,develops a sort of intelligent power regulator with powerful function and high reliability combined with the technology of microcontroller.Gaining a voltage signal from the output of rectifier,the microcontroller makes judgment based on its inner program and achieves regulation of power by outputting PWM waves to control the on-off ratio of TRIAC.All interrelated parameters can be changed via an input of external and are saved in E2PROM.This design can also be applied to many other kinds of solid-state relays.Different ways to trigger and different ranges of current to control can be realized by replacing different solid-state relays and downloading different programs.
