变频器中缺相检测的软件实现方法

A method of phase lack detected in inverter through software technology

变频调速技术是近年来发展起来的一种新兴技术,随着电力电子器件,计算机技术的发展,交流变频调速已取得了巨大的进步。同时,交流变频调速器作为一个新兴的产业正处在蓬勃发展之中,各种通用性变频器与高性能变频器的产品层出不穷。变频器的功能越来越丰富,保护越来越可靠。本文提出了变频器中的缺相保护的一种软件的实现方法,此方法已在所开发的系列产品中得到了应用,实验证明具有良好的可靠性与可信度。

The Frequency Conversion Adjusting Speed Technology has become a new technology nowadays. With the development of power electronics apparatus and computer technology, alternating Frequency Conversion Adjusting Speed Technology has made a great progress. Meanwhile, as a new and developing industry, more kinds of general and high-capability inverter have been produced and sold in the market, their functions become rich and they also run steadily and reliably. The paper mainly focuses on a method of phase lack protected in inverter through software technology, this method has already been applied in many developed product series, that＇s to say, its reliability and credibility have greatly been proved.
