摘　　要：采用数字合成技术制作了三相正弦波信号发生器,详细的分析了其电路工作原理和参数的选择,并将VBA的强大编程功能应用到对数据点的计算中。实验结果表明该设计所生成的三相正弦波具有频率精确度高、波形失真小、幅值稳定等优点,是各种测量和控制电路中理想的单相和三相基准正弦信号发生器。This paper uses digital synthesis technology to made a three-phase sinusoidal wave signal generator. The working principle of circuit and parameters selection are analysed in detail. Moreover the strong VBA programming function is applied to the calculation of data points. The experimental results show that the design of the generated three-phase sinusoidal wave has frequency with high precision, small waveform distortion, advantages of stable amplitude, It is an ideal single-phase and three-phase reference sinusoidal wave signal generator, in a variety of measurement and control circuits.
