摘要

本文研究了提高变频器抗短期供电中断能力的问题。提出了带开关结构的变频器-双速异步电动机系统的电驱动概念。研究结果表明，双输入电源变频器的发展是合理的，因为它几乎可以排除电源同时故障。考虑了两个变频器的电力驱动，由独立输入提供的高速和低速绕组以及具有两个直流链路的变频器的电力驱动。本文提出了变频器的特点是根据机组的性能将变频器从高速绕组切换到低速绕组(反之亦然)。它代表了已开发的vfd的实验研究结果。

Variable frequency drives with two-speed asynchronous electric motors

The paper considers the issues of enhancing immunity of the variable frequency electric drives (VFDs) c to short-term power supply interruptions. It proposes the concept of electric drives of the frequency converter-two-speed asynchronous motor system with switching structures. It is proved that development of VFDs with supply from two inputs is reasonable as they almost exclude simultaneous failures of power supply. Electric drive with two frequency converters, high and low speed windings supplied from independent inputs and electric drive with the frequency converter featuring two DC links are considered. The paper provides the VFD distinctive feature of which is switching the frequency converter from the high speed winding to the lowspeed one (and vice versa) dependent on the unit performance. It represents results of experimental research of the developed VFDs.
