DC gerilimi AC gerilime dönüştüren eviriciler (invertörler), güç elektroniği alanında en çok
kullanılan devre türlerinin başında gelmektedir. Anahtarlamalarla DC gerilimden AC gerilime dönüşüm
esnasında, çıkış geriliminde harmonikler oluşmaktadır. Harmonikler ise enerji/güç sistemlerinde güç
kalitesini belirleyen parametrelerin başında yer almaktadır. Dolayısıyla evirici devrelerinin çıkışındaki
harmoniklerin elenmesi/bastırılması önem arz etmektedir. Bu eleme işleminde ise çok değişkenli
karmaşık denklem sistemlerinin çözülmesi gerekmektedir. Gerçekleştirilen çalışmada, seçilen
harmonikleri elemek için en uygun anahtarlama açılarını, sekiz farklı metasezgisel algoritma/yaklaşım
(geri izleme arama, guguk kuşu arama, elektromanyetik alan optimizasyonu, harmoni arama, Harris
şahinleri optimizasyonu, dahili/iç arama, girdap arama, Yin-Yang-çifti optimizasyonu) ile hesaplayan
yazılım geliştirilmiştir. Kullanıcı dostu arayüze sahip yazılım ile seçilen türdeki evirici devrelerinde,
belirlenen harmonikler hızlı, kolay ve etkin bir şekilde elenebilmekte; sonuçlar hem sayısal hem de
grafiksel olarak gözlenebilmektedir.

THE HARMONIC ELIMINATION IN INVERTERS WITH METAHEURISTIC APPROACHES

Öz

Inverters which convert DC voltage into AC voltage are widely used in the field of power
electronics. During the conversion from DC voltage to AC voltage, some of the harmonics can occur.
Harmonics which are one of the most important parameters in the field of energy/power systems
determine the power quality. Therefore, one of the crucial steps is the elimination/suppression of
harmonics in the outputs of the inverters. It is required to solve complex equations with multiple variables
in this elimination process. In this study, a software is developed and eight different metaheuristic
algorithms/approaches (backtracking search, cuckoo search, electromagnetic field optimization, harmony
search, Harris hawks optimization, interior search, vortex search, Yin-Yang-pair optimization) are used
for the elimination of the chosen harmonics by determining suitable switching angles. The desired
harmonics are eliminated in the chosen inverter circuits via the software with a user-friendly interface
easily, fast and effectively, and the results can be observed both numerically and graphically through the
this software.
