矢量控制交流变频驱动器

AC Variable Frequency Driver With Vector Control

介绍了一种矢量控制交流变频驱动器的构成原理，详细地介绍了一种间接磁场定向的方法。同时还介绍了一种过流保护措施，揭示了矢量控制系统动态响应速度快的根本原因．

In this paper,the configuration theory of AC variable frequency driver with vector controlis in troduced. A concept of the indirect field oriented control is given in details.A method ofprotection for overcurrent and the major cause of vector control system offerring quick dynam-ic response are also presented。
