摘要
介绍了利用斩波式串级调速闭环系统，以实现高功率因数条件下压缩空气站的送气恒压、供气量与压缩机主轴电机转速正比连续可调的节能运行方案。
The chopper mode cascad control led closed-loop system is introduced in this paper.This approach can keep the pressure constantly under high power and the volume of the compressed-air is adjustable by adjusting the speed of the driving motor.
