Abstract

The space vector pulse width modulation (SVPWM) technique was tested on 6-switched 3-level inverter by this study. 6 IGBT semiconductor switches were used in inverter topology and coupled inductors were used in the output stage of the inverter. 6-switched 3-level inverter was obtained using inductors voltages. With using fuzzy logic controller the required switching signals were generated. SVPWM technique was used to produce these signals. It was aimed to reduction of output current’s harmonic components with used modulation technique. The inverter performance was investigated using RLC load in simulation studies. Load harmonic values were analyzed by fast fourier transform (FFT) and it was observed the harmonic amounts in the current. The fact that the resulting harmonics contain very low values has shown that the desired result was achieved successfully.

Özet

Uzay vektör darbe genişlik modülasyonu (UVDGM) tekniği bu çalışma ile 6-anahtarlı 3-seviyeli evirici üzerinde denenmiştir. Evirici topolojisinde 6 adet IGBT yarıiletken anahtar kullanılarak eviricinin her bir çıkış uçlarına çift sarımlı bobinler bağlanmıştır. Bobin gerilimlerinin kullanılmasıyla 6 anahtar ile 3 seviyeli evirici elde edilmiştir. Bulanık mantık denetleyici ile yarıiletken anahtarların çalışması için gerekli sinyaller üretilmiştir. Bu sinyaller, uzay vektör darbe genişlik modülasyon tekniği ile üretilmiştir. Kullanılan modülasyon tekniği ile çıkış akımı harmonik bileşenlerinin azaltılması amaçlanmıştır. Benzetim çalışmalarında RLC yük kullanılarak evirici performansı incelenmiştir. Yükteki harmonik değerler Fast Fourier Transform (FFT) ile analiz edilmiştir. Akımda oluşan toplam harmonik bozulma (THD) miktarlarının % 1.1 - % 1.5 değerleri arasında olduğu tespit edilmiştir. Bu değerler istenilen sonuca başarıyla ulaşıldığını göstermiştir.
