SVPWM inverterin çoklu darbeler yöntemiyle harmonik analizi

Abstract

Uzay Vektör Modülasyon (SVM) tekniği asenkron motor kontrolünde üç fazlı gerilim beslemeli inverter için popüler ve önemli bir PWM tekniğidir. Bu çalışmada Uzay Vektör PWM (SVPWM) inverterin çoklu darbeler yöntemini kullanarak yapılan harmonik analizi incelenmiştir. Çoklu darbeler yöntemi çıkış PWM dalga şeklinin her bir pozitif ve negatif darbesinin Fourier katsayılarını hesaplamakta ve tüm PWM çıkış sinyalinin Fourier katsayılarını hesaplamak için süperpozisyon ilkesini kullanarak birbirleriyle toplamaktadır. Harmonik genlikleri; doğrusallaştırma, tarama tabloları kullanımı ya da Bessel fonksiyonları olmaksızın bu yöntemle doğrudan hesaplanabilir. Bu çalışmada, değişken parametre değerleri için SVPWM uygulamasından elde edilen sonuçlar, çoklu darbeler yöntemiyle elde edilen sonuçlarla karşılaştırılmıştır.
