摘要
将空间矢量调制方法与传统的移相式空间脉宽调制(SPWM)方法相结合,并应用于级联型结构,提出了一种电压前馈解耦型矢量控制方法,并在三单元级联型逆变器试验装置上进行了验证。提出的空间矢量脉宽调制控制策略具有动态响应好、能准确平衡各开关器件的负荷、容易实现的特点,系统仿真与试验结果表明,该系统具有良好的动、静态性能。
A new space vector modulation combined with phase-shifted SPWM approach is utilized to cascaded multilevel inverters. And a feed forward voltage decoupling vector control method is presented. The proposed approach has some advantages, such as good dynamic regulation performance, balance of switching components power, easy realization. It is verified in a three-cell cascaded laboratory inverters system. Simulations and experimental resuits indicate the system has good dynamic and static state performance.
