摘　　要：本文介绍一种采用矢量分析,利用矢量积分器,通过译码器,坐标转换,由有限个平面矢量本文用6个平面矢量),产生三相准正弦波的方法。给出了原理和实现方法。最后,通过实验证明此方法是相当成功的,并给出了二个相位差互为90°的二相正张波讯号。In this paper, we present a method of generating three-phase sine signals using the vector analysis, vector integrator, coder, coordinate conversion, and with the help of limited flat vectors(here are 6 flat vectors). The principle and the practical method are presented here and they can be proved efficient through experiment. At last two (?)ine signals which are in quadrature with each other are given.
