A Power Factor Correction Buck Converter-Fed Switched Reluctance Motor with Torque Ripple Suppression

Abstract EN

The switched reluctance motor (SRM) suffers the main drawback of torque ripples, and a buck converter-fed SRM motor drive has been proposed to suppress torque ripples and correct a power factor in this paper.

The buck converter reduces the torque ripple by supplying appropriate DC-link voltage; meanwhile, the buck converter realizes a function of power factor correction at AC mains.

An enhanced performance has been obtained on speed control and power quality improvement.

An experimental SRM motor drive is formed, and the experimental results show that the proposed drive possesses an improved function with suppression of torque ripples and power factor correction.
