Power quality improvement technique using LED driver is presented in this paper. Harmonics is one of the major factors that affect the power quality of conventional grid or microgrid. Electrical loads are connected to the main grid as a common bus which is known as Point of Common Coupling (PCC). Harmonics are generated from different power supply units, rectifiers, power converters, UPS, generators, magnetic devices and LED lights. In this research, the harmonics compensation unit is incorporated into a LED driver which is capable of eliminating harmonics from PCC where the residential loads are connected. Half controlled rectifier is used for LED driver and the switches are controlled by the proposed control algorithm to reduce the harmonics on the PCC voltage. Fast and efficient algorithm has been utilized for the system. The simulation and experimental results are presented to verify the effectiveness of the proposed method.
