摘　　要：针对传统的交流调压器难以满足实时、精确调压和稳压的问题,设计了一种基于单片机的三相调压自动控制系统,详细介绍了系统的硬件电路和软件的实现。该系统以AT89C51单片机为控制核心,可实时监测电压信号的变化,实现在设定电压下的手动、自动调压功能。该系统还可以实现0.01V以上电压采集精度、0～400V之间升压、降压及稳压的自动控制功能。试验结果表明,该系统具有电路简单,工作可靠性强和自动化水平高等优点。For problems that traditional AC voltage regulator is difficult to meet with real-time, precision regulator and voltage stabilization, an automatic control system of three-phase voltage regulating based on single-chip microcomputer was designed, realization of hardware circuit and software of the system were introduced in details. The system takes AT89C51 single-chip microcomputer as control core, can real-timely monitor change of voltage signal and achieve manual, automatic voltage regulating function according to set voltage. It also can achieve 0. 01 V voltage collection precision, automatic control functions of 0-400 V boost, buck and stabilization of voltage. The experiment results showed that the system has advatages such as simple circuit, strong work reliability and high automation level.
