Matris çevirici kontrol tekniklerinin bilgisayar ortamındaki benzetimi

Bu çalışmada, girişindeki 3 fazlı alternatif sinyalleri çıkışında değişik frekans ve genliğe sahip 3 fazlı sinyallere dönüştüren, AA-AA matris çeviricilerin yapısı incelenmiştir. Venturini ve uzay vektör modülasyon kontrol teknikleri kullanılarak yük akımlarının bilgisayar ortamında ki benzetimleri yapılmıştır. Uzay vektör modülasyon tekniğinde değişik bir anahtarlama yöntemi kullanılmıştır. Her iki kontrol tekniğinde de kullanılan modülasyon oranının değiştirilmesinin yük akımları üzerindeki etkileri analiz edilmiştir. Çalışma sırasında iki kontrol tekniğinde de aynı anahtarlama frekansı kullanılarak, değişik çıkış frekanslarında benzetim çalışmaları yapılmış ve elde edilen sonuçlar sunulmuştur.

In this study, the structure of matrix converters, which have three phase AC signals at the input convert to the three phase variable frequency and amplitude AC signals at the output were examined. The simulation of load current, using Venturini and space vector modulation control techniques were implemented by using computer. A different switching method has been used in space vector modulation tecniques. Changing the modulation ratio used in both control techniques, the effect of load current was analysed. In order to compare during process, same switching frequency was used for both control techniques and at the different output frequencies simulation has been implemented and the results presented.
