Nova modulação vetorial para o controle da tensão do ponto central do divisor capacitivo do conversor com ponto neutro grampeado

Abstract: This paper presents a new space vector modulation strategy for the dc capacitor voltages control of neutral point clamped converters. By defining the neutral point current it is possible not only to ensure the balance of the dc voltages as well as to guarantee the elimination of low frequencies harmonic in neutral-point voltage under all load conditions in the entire converter linear operation region. Two switching sequences are explored to show the flexibility of propose method. Experimental results are prese… Show more
