Abstract

Nonlinear loads generate disturbances in the power grid, which impact the grid voltage quality. These also generate reactive power, which causes losses in the transmission and distribution systems. It needs to control the power quality of the grid as well as the power, due to the nonlinear loads. This research presents a new controller for Bridgeless Boost Power Factor Corrective PFC BBPFC rectifiers to improve the Total Harmonic Distortion THD of the utility grid along with the power factor on the grid. The input rectifier bridge in conventional boost PFC CBPFC rectifiers are discarded in bridgeless rectifiers to reduce complexity and increase the overall efficiency. The P and Q powers are controled through inner current loop in the improved algorithm. The reference current is calculated in the inner control loop through innovative filtering and signal processing. The inner current loop generates PWM switching signals by using PI controller. Analytical resolution of the suggested the technic of controller is presented in details. The performance of the controller which is adviced is confirmed for 300W rectifier by using PSIM circuit simulations.

Tek Fazlı Köprüsüz Yükseltici PFC Doğrultucular İçin PQ Kontroller

Abstract

Doğrusal olmayan yükler şebeke geriliminin kalitesini etkileyen harmonikler oluşturmaktadır. Hemde iletim ve dağıtım sistemlerinde kayıplara sebep olan reaktif güç üretmektedirler. Doğrusal olmayan yükler nedeniyle şebekenin güç faktörünün yanı sıra güç kalitesinin de kontrol edilmesi gerekmektedir. Bu araştırmada, şebekenin güç faktörünün yanı sıra toplam harmonik bozulma değerini THB iyileştirmek için kullanılan köprüsüz yükseltici güç faktörü düzelticileri KYGFD için yeni bir kontrol algoritması sunulmuştur. Karmaşıklığı azaltmak ve genel verimliliği artırmak için köprüsüz dönüştürücülerde geleneksel yükseltici GFD konvertörlerde bulunan köprü doğrultucu ortadan kaldırılmıştır. Önerilen algoritmada iç akım kontrol döngüsü ile aktif ve reaktif güç kontrol edilmiştir. İç kontrol döngüsünde yenilikçi filtreleme ve sinyal işleme yöntemleri kullanılarak referans akım hesaplanmıştır. İç akım döngüsü PI kontrolör kullanarak PWM anahtarlama sinyallerini üretmektedir. Önerilen kontrol tekniğinin analitik analizi detaylı olarak sunulmuştur. Önerilen kontrolörün performansı PSIM devre simülasyonları kullanılarak 300W dönüştürücü için doğrulanmıştır
