基于89S52单片机的无级功率控制器设计

Design of Continuously Variable Power Controller based on 89S52 Single-Chip Microcomputer

采用89S52单片机通过交流电信号过零检测、同步控制可控硅的导通角的方式实现功率的无级控制。所设计的控制器的功率可任意设置,并具有数码管显示功能和定时开关控制功能,此外,控制器上的串行口可实现远程控制。

Based on 89S52 single-chip microcomputer, the continuously variable power control is achieved by the AC single zerocrossing detection and the synchronous control of the thyristor＇s turn-on angle, The designed controller＇s power can be setup continuously, and it can be displayed digitally and controlled to turn on-off timely, And further, remote control can be implemented by the serial port on the controller.
