摘要

开关磁阻电机(SRM)驱动器作为调速和伺服应用的可行候选,正受到越来越多的研究人员和工业界的关注。将SRM的独特功能与使用的简单高效的功率转换器相结合,出现了一种优越的电机驱动系统,与其他交流或直流电机驱动系统相比,它可能更适合许多应用。尽管多年来出现了许多用于SRM驱动器的转换器,但是每个驱动程序都有自己的优点和缺点,并且在提供新驱动程序时,总是在获得一些优点和失去一些优点之间进行权衡。本文提出了一种开关磁阻电动机的新型驱动器。驱动器具有零电流开关。这意味着所有的开关操作都是在相电流越过零电平时完成的,因此它降低了开关过程中的总功率损耗。还提供了更快的上升和下降速度的电流,这有助于电机运行在更高的速度时,谐振现象被采用。关键词:开关磁阻电机,谐振驱动电路,SRM驱动,谐振驱动。

A New Resonant Driver for Switched Reluctance Motor
The switched reluctance motor (SRM) drive is receiving increasing attentions from various researchers as well as industry as a viable candidate for adjustable speed and servo applications. Combining the unique features of an SRM with simple and efficient power converter that is uses, a superior motor drive system emerges which may be preferable for many applications compared to other AC or DC motor drive systems. although a number of converters have emerged over the years for SRM drives, but every single driver has its own advantages and drawbacks and there has always been a trade-off between gaining some of the advantages and losing some when a new drivers is offered. In this paper we present a new driver for switched reluctance motor. The driver features zero-current switching. It means all the switching operations are done when the phase current crosses the zero level, therefore it reduces the overall power loss in the switching process. Also provides faster rate of rise and fall of current which helps the motor to operate at higher speeds when the resonance phenomenon is employed. Keywords: Switched Reluctance Motor, Resonant Drive Circuit, SRM Drive, Resonant Driver.
