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. Different space vector modulation (SVM) strategies are proposed 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 shows the advantages of low current harmonic injection, low output voltage ripple and a feature of variable structure to achieve continuous service when it is powered from a utility with low power quality. The feasibility of the proposed four-pole three-phase rectifier is verified by simulation and experimental results
