摘　　要：SVPWM是电力电子技术教学中的重要内容,本文对空间矢量调制的教学重点做了一个较为全面系统的梳理。重点阐述SVPWM的核心思想,特别是三相正弦交流电SVPWM的基本原理,严格证明了三相电压的空间矢量相等与线电压相等等价。同时,证明在SVPWM下,逆变器输出的最大圆为基本空间矢量构成的正六边形的内接圆、直流母线电压利用率提高了约15.4%。SVPWM is an important content in the teaching of power electronic technology.In this paper,the teaching focus of space vector modulation is comprehensively and systematically combed.This paper focuses on the core idea of SVPWM,especially the basic principle of three-phase sinusoidal AC SVPWM.At the same time,it is proved that under SVPWM,the maximum circle of the inverter output is a regular hexagon formed by the basic space vector,and the utilization rate of DC bus voltage is increased by about 15.4%.
