摘　　要：三电平逆变器在中压大功率场合应用很广泛。由于中点电位波动等问题使三电平逆变器的控制较复杂。文章分析了空间矢量对中点电位波动的影响 ,仿真结果说明采用空间电压矢量控制方法时 。Three level inverters have found wide applications in medium voltage high power applications. Due to neutral point potential fluctuation the inverters are difficult to control. In the paper the influence of space vectors on the neutral point potential fluctuation is investigated. It is verified by simulation results that selecting redundant small space vectors is an effective way of control neutral point potential fluctuation when using space vector PWM technique.
