摘要
三电平逆变器以其优越的性能已经逐步成为大容量、中高压电机调速的主要实现方式之一。文章从扇区和区域的划分、工作模式的判断、开关矢量作用时间的计算以及空间电压矢量作用顺序的确定等几个方面介绍了三电平空间矢量脉宽调制的算法原理。最后给出了用MATLAB仿真的结果,证明了三电平逆变器的优点。
Three-level converter has become one of the main implementation modes of high capacity and high voltage motor speed adjustment by its superior performance. This paper introduce the principle of the algorithm of the three-level SVPWM from the division of sectors and regions, the judgment of work mode, the calculation of the time of the switch vec tor and the determination of the spatial voltage vector action sequence. Finally, the results of MATLAB simulation are presented to prove the advantages of the three-level converter.
