摘要
利用SVPWM控制技术产生的正六边形旋转磁场,采用在基本电压矢量之间巧妙插入零电压矢量办法,利用空间矢量概念形象而深刻阐述了逆变器变频原理的实现,并得出了一些有意义的结论。这对准确而全面理解SVPWM控制技术、深刻掌握交流调速系统有关内容具有重要意义。
In this paper,SVPWM control technology is utilized to produce hexagonal rotating magnetic field,and a method is employed by inserting zero voltage vectors between the basic voltage vectors skillfully.Then the idea of Space Vector is used,and the realization of the principle of inverter variable frequency is explained vividly and deeply.Lastly some useful conclusions are gotten.It is important for students to understand and master the knowledge of SVPWM technology and AC drive system accurately and comprehensively.
