Modified Carrier Based PWM Control for Grid-Connected Single Phase Transformerless Inverter

Year 2022, Volume: 12 Issue: 2, 7 - 14, 11.12.2022

Abstract

In this paper, the performance comparison of different carrier signal based modulation techniques is presented for grid-connected single phase H6-II type transformerless inverter for same switching frequency. Here, carrier signals used in multi-level and mostly three-phase inverters and new carrier signals derived from them are extended for controlling single-phase H6-II type inverter. System performance is evaluated with observed inverter output voltage and current waveforms, measured current and voltage, and calculated efficiency and total harmonic distortion (THB) for the created carrier-based pulse width modulation (PWM) control techniques. Test results show that modified carrier based PWM control techniques performs better than the traditional technique in terms of efficiency, THB and leakage current.

Year 2022, Volume: 12 Issue: 2, 7 - 14, 11.12.2022

Abstract

Bu çalışmada aynı anahtarlama frekansı için şebeke bağlantılı tek fazlı H6-II tipi transformatörsüz evirici için farklı taşıyıcı işaret temelli modülasyon tekniklerinin performans karşılaştırılması sunulmaktadır. Burada çok seviyeli ve çoğunlukla üç fazlı eviricilerde kullanılmakta olan taşıyıcı işaretleri ve bunlardan türetilmiş yeni taşıyıcı işaretler tek fazlı H6-II tipi eviricin kontrolü için sunulmaktadır. Oluşturulan taşıyıcı temelli darbe genişlik modülasyonu (DGM) kontrol teknikleri için sistem performansı, gözlemlenen evirici çıkış gerilim ve akım dalga şekilleri, ölçülen akım ve gerilim ve hesaplanan verim ve toplam harmonik bozunum (THB) ile değerlendirilmiştir. Test sonuçları, modifiye edilmiş taşıyıcı tabanlı DGM kontrol tekniklerinin verimlilik, THB ve kaçak akım açısından geleneksel teknikten daha iyi performans sergilediğini göstermektedir.
