摘　　要：为了实现对三相交流电源输出电压和频率的高精度控制,设计了一种基于AD C841单片机控制的三相程控交流电源,给出了系统结构框图、硬件设计电路和软件流程.运行结果表明,系统具有输出电压和频率变化范围大,波形质量好,控制方便等优点.In order to realize the high precision control of output voltage and frequency of the three-phase AC power supply, a three-phase programmable power supply with ADuC841 single-chip controller was designed, and the block diagram of system, the hardware design circuit, and the software flow chart were given as well. The running result shows the system has a widely variable range of output voltage and frequency, good waveform, easy control and etc.
