Abstract

This paper presents a comparative analysis and design procedure of a four-pole (eight switches) three-phase rectifier having a neutral point to the input filter capacitor. Space vector modulation (SVM) is developed for this PWM rectifier including the neutral path. This topology is compared with the conventional PWM rectifier using three poles (six switches). The proposed rectifier structure shows the advantages of low current harmonic injection, low output voltage ripple, and better control flexibility for continuous service in electric system with low power quality. The feasibility and features of the proposed four-pole three-phase rectifier is verified by simulation and experimental results
