In this paper, a new modulation approach, Sinusoidal Area Matching Modulation (AMM), is proposed for multilevel inverter (MLI) systems. While the conventional Nearest Level Control (NLC) method is based on rounding the reference signal to the nearest level, the AMM method is based on the principle of field equality between the sinusoidal reference signal and the cascaded structure of the output. This approach provides average power accuracy and lower harmonic distortion (THD), especially in inverter systems where the output voltage waveform is cascaded. While the THD rate obtained with the AMM method was reduced to 8.91%, it was calculated as 9.36% with the NLC method. The method is applied to an asymmetric Cascaded H-Bridge (CHB) topology and evaluated through detailed simulation studies. The results show that the proposed AMM technique offers lower THD and improved RMS performance compared to the NLC method. Moreover, the analysis for different peak values of the sine wave shows that the AMM also exhibits superior performance under variable amplitude conditions.

Bu çalışmada, çok seviyeli inverter (ÇSE) sistemleri için yeni bir modülasyon yaklaşımı olan Sinüzoidal Alan Eşleştirme Modülasyonu (AEM) tekniği önerilmiştir. Geleneksel En Yakın Seviye Kontrol (NLC) yönteminde, referans sinyalin en yakın seviyeye yuvarlanması esas alınırken, AEM yöntemi sinüzoidal referans sinyali ile çıkışın basamaklı yapısı arasındaki alan eşitliği ilkesine dayanmaktadır. Bu yaklaşım, özellikle çıkış gerilim dalga formunun basamaklı üretildiği inverter sistemlerinde ortalama güç doğruluğu ve daha düşük toplam harmonik bozulma (THD) elde edilmesini sağlar. AEM yöntemiyle elde edilen THD oranı %8.91’e düşerken, NLC yöntemiyle bu oran %9.36 olarak hesaplanmıştır. Yöntem, asimetrik yapıdaki Kaskat H-Köprü (CHB) topolojisine uygulanmış ve detaylı simülasyon çalışmaları ile değerlendirilmiştir. Elde edilen sonuçlar, önerilen AEM tekniğinin NLC yöntemine kıyasla daha düşük THD ve gelişmiş RMS performansı sunduğunu ortaya koymaktadır. Ayrıca sinüs dalgasının farklı tepe değerleri için yapılan analizlerde, AEM'nin değişken genlik koşullarında da üstün performans sergilediği gözlemlenmiştir.
