关于提高变频器调频速度的研究

Research of Speed Increasing of Inverter Frequency Tuning

本文介绍了作者的一项专利技术。对于需要比较快速、比较频繁地调整变频器频率应用场合,目前的通用变频器就很难满足这个需要,尤其是在大惯性负载上使用变频器时,须将升、降频(特别是降频)速度设置的比较慢,以适应由于惯性造成的电机转速的滞后。本专利技术克服上述传统变频器目前存在的缺陷,在传统变频器上增加比较简单并业已成熟的换相技术,为变频器的制造提供了一种新的附加技术。

The article introduces a patent technology. In situations where inverter frequency needs to be quickly and frequently tuned, main-stream general purpose inverters are hard to meet the requirement. Especially situation with big inertia load, speed of increasing or decreasing must be configured slow to meet the delay of motor speed resulted from inertiaif The patent technology comes over the above defects with the simple but mature phase changing technology and becomes a new additional technology for inverter manufacturing.
