A Novel Method of Space Vector Pulse Width Modulation With Constraints [PDF]

, 2013
为解决传统调制方法中的最小脉宽问题,提出了一种带约束的电压空间矢量脉宽调制(SPACE VECTOr PulSE WIdTH MOdulATIOn,SVPWM)方法。首先,建立新的三相桥臂坐标,取消了扇区的划分和判断;其次,将基本电压空间矢量由8个减小为3个,并将其作用时间与三相桥臂的导通时间一一对应;再次,通过增加约束条件,将传统SVPWM方法的调制过程及其结果离散化,从而避免了窄脉宽的出现;最后,给出了一种快速的计算策略,其计算量仅与SVPWM方法一个扇区的计算量基本相同。相对于SVPWM方法 ...
