Abstract

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). The most important aim of these changes is undoubtedly to increase energy efficiency. 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.

Özet

Günümüzde gelişen teknolojiye paralel olarak aydınlatma alanında yeni nesil ürünler ortaya çıkmakta ve mevcut sistemlerde iyileştirmeler yapılmaktadır. Bu iyileştirmeler genellikle konvansiyonel aydınlatma ürünlerinin ışık yayan diyotlarla (Light Emitting Diode - LED) değiştirilmesiyle gerçekleştirilmektedir. Bu değişimlerin en önemli amacı şüphesiz enerji verimliliğini artırmaktır. LED’ler uzun ömür, yüksek ışıksal etkinlik, renk kontrolü ve çevre dostu gibi önemli özelliklere sahip olmasına rağmen çalışma karakteristikleri gereği bir sürücü devresine ihtiyaç duymaktadırlar. Bu sürücü devrelerinin içerdiği güç elektroniği elemanları LED’lerin sistemden harmonikli akım çekmelerine neden olmaktadır. Bu nedenle LED sürücülerin güç kalitesi üzerine etkilerini analiz etmek ve yorumlamak çok önemlidir. Bu çalışmada, ticari olarak kullanımda olan farklı üreticilere ait LED sürücülerin harmonik içeriği, toplam harmonik bozulumu ve güç faktörü değerleri incelenmiştir. Ayrıca aynı sürücü üzerinden farklı sürme akımlarında ölçümler yapılarak sürme akımlarının güç kalitesine etkisi ortaya konulmuştur. Çalışma sonucunda, farklı üreticilere ait LED sürücülerin güç kalitesi üzerine önemli etkilerinin olduğu ve bu etkilerin sürme akımına bağlı olarak değiştiği görülmüştür.
