摘　　要：SVPWM是“电力电子技术”教学中的重要内容,SVPWM教学中存在若干难点,目前的教材中都没有提及相电压和线电压的波形,难以给学生直观的印象,学生也难以了解SVPWM的工作机理。本文简洁地推导了SVPWM的相电压和线电压,画出相关波形,并对波形进行了分析,对SVPWM的教学有积极参考价值。SVPWM is an important content in the teaching of Power Electronic Technology.There are some difficulties in SVPWM teaching.The waveform of phase voltage and line voltage is not mentioned in the current textbooks.It is difficult to give students an intuitive impression and understand the working mechanism of SVPWM.In this paper,the phase voltage and line voltage of SVPWM are simply deduced,and the related waveforms are drawn and analyzed.It has positive reference value for SVPWM teaching.
