This paper presents, a Radial Basis Function Network (RBFN) controller based boost type Vienna Rectifier, which is engaged in a single stage energy conversion in the wind turbine system (WTS). The boost type Vienna Rectifier converts AC into DC with an enhanced voltage of a 230V AC to 400V DC in a single stage conversion, along with the benefits of the low voltage stress across switches (50% of DC-link voltage), reduced harmonics, sinusoidal input current shaping, and improved power factor. This sort of AC/DC conversion is adequate for low voltage DC distribution, telecommunication systems, and data centers etc. This paper presents the comparative analysis of single stage Vienna Rectifier over two-stage energy conversion (Diode bridge rectifier + Boost converter) for 1kW wind turbine system and results are validated in MATLAB/Simulink. © 2017, Gazi University Eti Mahallesi.
