摘要
介绍了以集成移相触发器TCA785、单片机、数字电位器为核心所构成的晶闸管电源控制仪的工作原理，它集同步检测、移相脉冲形成、保护、手动控制与自动控制功能于一体，可用于对负载的恒电压或恒电流控制。
：A kind of power control meter based on integrating TCA785 and a piece of microcomputer，digital rugulator is introduced in the article．The meter consists of synchronizing test，moving phase puls producter and safeguarding set，and can be worked in manual－control mode or auto－control mode．It can be used in controlling steady voltage and steady current of load．
