Saravana, Prakash, P.Kalpana, R.Singh, B.2020-03-302020-03-302018Proceedings of 2018 IEEE International Conference on Power Electronics, Drives and Energy Systems, PEDES 2018, 2018, Vol., , pp.-https://idr.nitk.ac.in/handle/123456789/7632This paper proposes a 20-pulse asymmetric multiphase rectifier (AMPR) suitable for medium and high-power applications. Unlike the other state-of-the-art 20-pulse delta connected autotransformers, the proposed delta connected AMPR has an ability to reduce input harmonics, maintains high efficiency and requires a magnetic rating of only 30.12% of the nominal load thereby a significant reduction in space, weight, and overall cost required are the salient features of the proposed AMPR. Firstly, the proposed AMPR configuration is simulated in MATLAB/Simulink environment for evaluating its viability under different loading conditions, and the results are illustrated. Also, a prototype is developed, and the experimental measurements obtained are presented to validate the feasibility and operability of the proposed AMPR. The proposed AMPR offers a total harmonic distortion of 3.7% and can operate at near-unity power factor complying with the IEEE and IEC standards. � 2018 IEEE.Book chapter
