Design and analysis of performance and power quality of a led driver

Today, in parallel with the developing technology, state of the art products are used in the lighting area and improvements are made in existing systems. These improvements are generally achieved by replacing conventional lighting products with light emitting diodes (LEDs Although LEDs have important features such as long lifetime, high luminous efficacy, color control, and eco-friendly, they need a driver due to their operating characteristics. The power electronics components in these drivers cause the LEDs to draw harmonic current from the system. Therefore, it is very important to analyze and interpret the effects of LED drivers on power quality. In this study, harmonic content, total harmonic distortion and power factor values of LED drivers of different manufacturers in commercial use have investigated. In addition, the effect of the driving currents on the power quality has determined by making measurements at the same driver at different driving currents. As a result of the study, it is seen that LED drivers which belong to different manufacturers have significant effects on power quality and these effects change depending on the driving current.
