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

Energies, 2021
In this paper, a novel approach to matrix-converter-based variable frequency drives is presented. It is proposed that these drives are used to provide or draw out reactive power from the power distribution line, keeping the power factor close to unit and,

Industrial Power Factor Analysis Guidebook.

, 1995
Power factor is a way of measuring the percentage of reactive power in an electrical system. Reactive power represents wasted energy--electricity that does no useful work because the electrical current is out of phase with the voltage.
