In this paper, a thorough analysis is carried out in order to achieve an optimal design of a forty-four pulse rectifier. In this study, a novel Multi-phase Shifting Autotransformer (MPSA) is introduced, discussed, simulated and implemented to forty-four pulse rectifier with acceptable power rates. Accordingly, the main purpose of the paper is focused on the power kVA rating reduction for power quality applications. It provides a more economical solution to achieve harmonic mitigation in electric power systems as compared with other rectifiers. The simulation and experimental results show that the input current THD is less than 3% using the proposed topology. The results indicate a significant reduction in the total cost and volume of the proposed forty-four pulse configuration in comparison with similar configurations. Also, it is shown that the proposed converter rating is about 42% of the DC load power.
