Power Quality Improvement for Isolated Luo Converter Fed Induction Motor

Abstract

In modern trends, the fast advancement in power semiconductor devices has augmented an ample chain of applications such as robotics, industrial, and numerous others. Converters are popular structures that are conventionally implemented with the regulation of voltage. However, they are having higher THD, lower PF with meager efficiency for power transfer. Harmonics distortions produced by power converter are fetching a severe concern for reliable operation of the system. All the same, a customary scheme using a rectifier with a capacitor has undesirable consequences and auxiliary losses. This paper enlightens the relative performance analysis of secluded Luo converter feeding dc motor for power quality improvement. The recommended topology provides the lessening of THD by utilizing a proportional-integral scheme along with a voltage follower approach. Performance for the intended converter is simulated in a MATLAB environment, providing an improved quality of power at AC mains.
