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.

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.
