Abstract

In this paper, the effect of carrier waveform variations on inverter output voltage in multilevel inverters is examined. For this aim, carrier waveforms with various frequency and amplitude are constructed and compared with the reference sinusoidal signals. The obtained PWM waveforms are then applied to the power switches of the inverter. A five-level inverter prototype implemented and the real-time signals are produced using dSPACE DS1103 controller board and software’s. The proposed multilevel sinusoidal PWM (SPWM) strategy is tested experimentally and the results obtained are presented.

Özet

Bu makalede, Çok Seviyeli Eviricilerde (ÇSE) taşıyıcı dalga şekli değişimlerinin evirici çıkış gerilimi üzerine etkileri incelenmiştir. Bu amaçla, farklı genlik ve farklı frekans değerlerine göre taşıyıcı dalgalar oluşturulmuş ve referans sinüzoidal işaretler ile karşılaştırılarak eviricinin güç anahtarlarını denetleyen Darbe Genişlik Modülasyonlu (DGM) sinyaller elde edilmiştir. Bunun için, bir 5-seviyeli eviricinin prototipi gerçekleştirilmiş olup eviricinin denetimi için gerçek-zamanlı sinyaller dSPACE firmasının DS1103 denetleyici kartı ve yazılımları kullanılarak üretilmiştir. Önerilen çok seviyeli Sinüzoidal DGM (SDGM) stratejisi deneysel çalışmalar ile test edilmiş ve deney düzeneği üzerinden alınan sonuçlar verilmiştir.
