摘要
文章以三电平 PWM变频器为例介绍了一种新型的双 PWM变频调速系统 ,此系统通过可控的整流部分来实现控制系统功率因数和无功功率的控制 。
A new dual PWM three level converter is introduced in this paper. The rectifier of this drives converter is active front end,it can fulfill drives system power factor and reactive power adjustment and make converter to be a clean power supply.
