PMSGs have higher efficiency and torque density which enables compact, direct-drive wind turbines. However, these systems do not have the benefit of allowing power electronics to process partial power as a DFIG would. This thesis analyzes a composite converter architecture for tying PMSG-based wind energy conversion systems to an AC grid that reduces the use of high-frequency switches. The system is a partial power processing converter featuring two processing paths, both of which are fed by a multi-port PMSG. The first path comprises a passive rectifier and line-frequency inverter. The second path utilizes an active rectifier and inverter which employ pulse-width modulation. The two inverters drive either end of an open-winding transformer. The line-frequency path uses reliable, efficient, and inexpensive diodes and switches to process the majority of the power. The high frequency path uses high frequency switches but only processes 10% of the rated power at most. A design framework for minimizing switch rating shows a reduction in high frequency switch-VA rating by 68%. This results in an overall loss reduction ranging between 46.8% and 53% depending on the extracted power. Control and modulation strategies and a maximum power point tracking algorithm are presented. Experimental results obtained from a laboratory prototype validate the performance and the effectiveness of the proposed converter architecture, and its control and modulation strategies. The voltage ripple present in the two dc-links of this system and RMS current stress placed on the dc-link capacitors is quantified. This approach opens up opportunities for integrating ac-collection networks through an efficient, reliable, and cost-effective energy conversion system."]},{"key":"dc:format","label":"Dc Format","values":["application/pdf"]},{"key":"dc:title","label":"Title","values":["A composite converter architecture for wind energy systems tied to an AC grid"]}]}],"canonical_facts":{"dc:contributor":["Banerjee, Arijit"],"dc:creator":["Paximadas, Jason Orestis"],"dc:date":["2024-05","2024-05-03"],"dc:description":["Submission original under an indefinite embargo labeled 'Open Access'.
