摘　　要：SVPWM是“电力电子技术”教学中的重要内容,而掌握空间矢量概念是学习SVPWM的基础,目前教学中普遍对于空间矢量的定义不够清晰严谨统一,逻辑关系比较混乱。本文结合最新研究进展给出三相电压的空间矢量的严格统一定义,并应用到三相正弦交流电和逆变器。同时对空间矢量的性质进行了研究,特别是澄清了空间矢量及SVPWM和3s-2s坐标变换的关系。SVPWM is an important content in the teaching of Power Electronic Technology,and mastering the concept of space vector is the basis of learning SVPWM.At present,the definition of space vector is not clear,rigorous and unified,and the logical relationship is chaotic.In this paper,a strict unified definition of space vector of three-phase voltage is given and applied to three-phase sinusoidal AC and inverter.At the same time,the properties of space vector are studied,especially the relationship between space vector,SVPWM and 3s-2s coordinate transformation is clarified.
