Abstract

Single-phase AC/DC converters with Power Factor Correction (PFC) circuit are used as full-wave
controlled rectifiers in many power electronics circuits to provide high standards of efficiency and improve power
quality. In parallel with the changes in the circuit topologies used, new algorithms are being developed in control
methods. In recent years, new control and modeling methods using fractional derivatives and integrals have been
developed. In this study, it is aimed to correct the power factor on AC side of the circuit and to keep the output voltage
constant at the desired value by using a boost converter for wireless energy transfer. Fractional order PI (FOPI)
controller is used to control output voltage and a classical PI controller is used to generate a reference current of boost
converter. The Particle Swarm Optimization method was used to optimize the controller coefficients. As a result of the
simulation studies, the power coefficient was kept at 0.99.

Kablosuz Enerji Transferinde Ortalama Akım Yöntemi ile Kesirli PI Kontrolör Kullanılarak Çıkış Gerilimin Kontrolü ve Güç Katsayısının Düzeltilmesi

Abstract

Güç Faktörü Düzeltme (PFC) devreli tek fazlı AC/DC dönüştürücüler yüksek standartlarda verim sağlamak ve güç
kalitesini iyileştirmek amacıyla birçok güç elektroniği devresinde tam dalga kontrollü doğrultucu olarak
kullanılmaktadır. Kullanılan devre topolojilerindeki değişikliklere paralel olarak kontrol yöntemlerinde de yeni
algoritmalar geliştirilmektedir. Son yıllarda kesirli türev ve integralin kullanıldığı yeni kontrol ve modelleme
yöntemleri geliştirilmektedir. Yapılan çalışmada kablosuz enerji transferinde yükseltici dönüştürücü kullanılarak
devrenin AC tarafında güç katsayısının düzeltilmesi ve çıkış geriliminin istenen değerde sabit tutulması
amaçlanmaktadır. Çıkış gerilimini kontrol için Kesirli PI kontrolör ve yükseltici dönüştürücünün referans akımını
üretmek için ise klasik PI kontrolör kullanmıştır. Kontrolör katsayılarının optimize edilmesi için Parçacık Sürü
Optimizasyon yöntemi kullanılmıştır. Benzetim çalışmaları sonucu güç katsayısı 0.99 değerinde tutulmuştur.
