基于单片机与TC787的智能化晶闸管控制电路

Digital and Intelligent SCR Trigger based on Microcontroller and TC787

介绍了一种基于AT89C52单片机与专用集成触发芯片TC787的晶闸管触发器,它结合专用集成触发芯片和数字触发器的优点,获得了高性能和高度对称的触发脉冲。它充分利用单片机内部资源,集相序自适应、系统参数在线显示、调节和各种保护功能于一体,可用于对负载的恒电压或恒电流控制。

A SCR trigger based on microcontroller and TC787 is introduced in this paper. It combines the merits of the Smart Power IC and digital trigger, and produces trigger pulses with perfect performance and high symmetry. Making full use of the resources of single 2 chip computer, it realizes phase self adaptive, protection and parameter adjustment on line. It can be used in controlling steady voltage and steady current of load.
