摘　　要：本文介绍了三电平空间矢量脉宽调制(SVPWM)的基本原理,根据空间矢量调制的规律,重点介绍了五种三电平SVPWM算法,并对它们各自的特点进行了分析,包括古典算法;参考电压分解SVPWM算法;基于线电压坐标系的SVPWM算法;基于60°坐标系的SVPWM算法:基于120°坐标系的SVPWM算法。最后针对上述五种算法,对三电平变换器中点电压的平衡控制进行了研究。The basic principle of three-level space voltage pulse width modulation is presented in this paper.According to the rule of space vector modulation,five kinds of three-level SVPWM algorithms are presented.They are：the traditional algorithm,correction reference voltage vector SVPWM algorithm,the algorithm based on line voltage coordinates,the algorithm based on 60 degree coordinates and the algorithm based on 120 degree coordinates.Finally,the neutral-point voltage balance control strategies for three-level converter are studied.
