Space Vector Modulation in Three-Phase Inverters: Theoretical Foundations, Simulation, and Applications

Abstract

This study comprehensively examines the theoretical foundation, simulation analysis, and application areas of Space Vector Pulse Width Modulation (SVPWM) used in three-phase inverters. Compared to traditional modulation techniques, SVPWM offers higher output voltage, lower Total Harmonic Distortion (THD), and improved energy efficiency. The simulation phase of the study was carried out in the MATLAB/Simulink environment. Through simulations, the accuracy and effectiveness of the method were evaluated, and both the advantages of SVPWM and the practical limitations were discussed, along with potential approaches for addressing these limitations in the future. This analysis highlights the potential of SVPWM, especially in industrial fields such as electric vehicles, renewable energy systems, and robotics.

Üç Fazlı İnverterlerde Uzay Vektör Modülasyonu: Teorik Temeller, Simülasyon ve Uygulamalar

Abstract

Bu çalışmada, üç fazlı inverterlerde kullanılan Uzay Vektör Modülasyonu (SVPWM) yönteminin teorik altyapısı, simülasyon analizleri ve uygulama alanları kapsamlı bir şekilde incelemektedir. SVPWM geleneksel modülasyon tekniklerine kıyasla daha yüksek çıkış gerilimi, daha düşük toplam harmonik distorsiyonu (THD) ve enerji verimliliği sağlamaktadır. Çalışmanın simülasyon aşaması MATLAB/Simulink ortamında gerçekleştirilmiştir. Simülasyonlarla yöntemin doğruluğu ve etkinliği değerlendirilmiş, SVPWM'in avantajları kadar pratikteki sınırlamaları ve bu sınırlamaların giderilmesi için gelecekte uygulanabilecek yaklaşımlar da tartışılmıştır. Bu analiz, özellikle elektrikli araçlar, yenilenebilir enerji sistemleri ve robotik gibi endüstriyel alanlarda SVPWM’in potansiyelini vurgulamaktadır.
