Application of Matrix VFD for Power Factor Improvement in LED Lighting Sources Loaded Power Distribution Lines

In this paper, a novel approach to matrix-converter-based variable frequency drives is presented. It proposed that these are used provide or draw out reactive power from the distribution line, keeping factor close unit and, simultaneously, performing their primary function of motor powering and speed control. This application required due need compensate for capacitive generated by light emitting diode lighting devices. study, compensation range drive determined, method extend range.
