交流变频调速系统的特点及其重要作用

Features and Importance of Variable Frequency Speed Regulation System

2 0世纪 6 0年代以后 ,由于电力电子技术、微机控制技术和矢量控制技术的发展 ,使得交流电机变频调速系统日趋完善 ,并且有取代直流调速系统的趋势。本文指出了交流变频调速系统的特点 。

Since 1960s,because of the development of the power electronic technology?the microcomputer control technology and the vector control technology,the AC motor variable frequency speed regulation system is being more and more perfect and is taking the place of the DC speed regulation system.This paper describes the features and the important roles in the industry area of the AC variable frequency speed regulation system.
