Dual Vienna Rectifiers with a Single Dc-link for Wind Energy Conversion System Applications

In this paper, dual Vienna rectifiers are proposed for Wind Energy Conversion System (WECS) applications with Open-End Winding (OEW) Permanent Magnet Synchronous Generator (PMSG). Due to the reduced number of controlled switches, the proposed topologies have reduced costs and high reliability. Besides, they provide a better power quality using the same number of controlled switches than conventional structures presented in the literature, making them very attractive options for industry applications. The system model, space vector modulation, and control strategy are given. Simulation results are provided in order to validate their performance and feasibility.
