Etkili Bir Hibrit Kontrol Tekniği ile Alçaltıcı Çevirici Tabanlı Üç Faz Aktif İzleyen AA-AA Gerilim Regülatörü

Abstract

Bu çalışma, alçaltıcı çevirici tabanlı anahtarlamalı mod aktif izleyen bir AA-AA gerilim regülatörü sunmaktadır. Regülatör topolojisi az karmaşıklık ve yüksek verimlilik sağlayacak şekilde makul sayıda eleman içermektedir. Literatürdeki benzer çalışmalardan farklı olarak, bu çalışmada regülatörün kontrolü için kapalı çevrim PID kontrolcünün yeni tasarlanan bir ileri beslemeli kontrolcü ile desteklenmesi tabanlı etkili bir hibrit kontrol tekniği önerilmiştir. Hibrit kontrol tekniği, giriş AA faz gerilimlerinin ideal saf sinüs dalgası olması ya da farklı harmonikler içermesi durumunda dahi iyileştirilmiş kalitede sinüs formuna yakın çıkış faz gerilimlerinin elde edilebilmesi için referans çıkış faz gerilimlerinin aktif izlenmesi cevabını arttırmaktadır. Regülatör topolojisi her bir çıkış fazının bağımsız olarak kontrol edilebilmesini sağlayan modüler bir yapıya sahiptir. Böylelikle regülatör, dengeli/dengesiz yıldız bağlı üç fazlı bir yükün ya da birbirinden bağımsız tek fazlı yüklerin beslenmesi için sinüs dalga formuna yakın çıkış faz gerilimlerinin elde edilebilmesine yardımcı olmaktadır. Sunulan üç fazlı regülatör ve kontrol tekniği simülasyon ve deneysel çalışmalarla test edilmiştir. Regülatöre ait laboratuvar test düzeneği 2.2 kW çıkış gücü, 0-300 Vp giriş faz gerilimleri (50 Hz) ve 0-200 Vp çıkış faz gerilimleri için tasarlanmıştır. Elde edilen sonuçlar, önerilen anahtarlamalı mod üç faz alçaltıcı tip aktif izlemeli gerilim regülatörünün farklı çalışma koşullarında %5 ten az THD (toplam harmonik distorsiyonu) değerine sahip istenen AA faz gerilimlerini sağlayabildiğini göstermektedir.

Three-phase Active Tracking AC-AC Voltage Regulator based on Buck Converter with an Efficient Hybrid Control Technique

Abstract

This study proposes a switch-mode three-phase active tracking AC-AC voltage regulator based on the buck converter. The regulator topology incorporates a moderate number of components with less complexity and high efficiency. An efficient hybrid control technique, based on a closed-loop PID controller that is supported with a new designed feedforward controller, is proposed for the regulator control different to the similar studies in the literature. The hybrid control technique augments the response of active tracking of the reference output phase voltages to achieve an improved quality close to sine-wave output phase voltages for either the input AC phase voltages that are ideal pure sine-wave or include various harmonics. The regulator topology has a modular structure for independent control of each output phase. So, the regulator can help to achieve close to sine-wave output phase voltages to supply a balanced/unbalanced wye-connected three-phase load or independent single-phase loads. The presented three-phase regulator and the control technique are tested with simulation and experimental studies. The laboratory set-up of the regulator is designed for 2.2 kW output power, 0-300 Vp input phase voltages (50 Hz), and 0-200 Vp output phase voltages. The results demonstrated that the proposed switch-mode three-phase buck-type active tracking voltage regulator can provide the desired AC phase voltages with less than 5% THD (total harmonic distortion) and low harmonics for different operating conditions.
