Comparative analysis of RBFN and fuzzy-SVPWM controller based boost type Vienna rectifier for 1kW wind energy conversion system

Abstract

In this paper RBFN (radial basis function network) MPPT controller based 3-f boost typeVienna Rectifier is designed for wind energy conversion system (WECS). The 3-Φ boost type Vienna rectifier is accomplished to convert AC/DC conversion from the renewable energy systems of AC generating units and/or fromAC mains. This kind of rectifiers is very impressive where a unidirectional power flow is adequate in the network with high power density. The AC/DC rectifier provides a sinusoidal input current, improved power factor and low ripple at the input side. An RBFN controller based proposed system configuration is designed for 1kW wind energy conversion system in MATLAB/Simulink with a step up voltage of 230 V to 400 V at a turbine base speed of 12 m/s and the results are validated. The performance analysis of an RBFN controller based circuit topology is compared with the fuzzy logic-based SVPWM (space vector pulse width modulation) controller.
