Abstract
Due to lack of conventional energy sources, world is moving towards wind energy as a substitute for the energy need. In this paper, fuzzy controller based boost converter is proposed to regulate maximum power point of wind turbine. Generally, the alternator overloadrestricts the potential of DWIG at low rotor speeds; by using boost converter high dc voltage is produced during low potential and low speed. The duty ratio of boost converter is regulated by fuzzy controller. Fuzzy logic controller is able to steppeak power for uncertain wind circumstances, and vigorous with respect to specification changes in turbine. The proposed system is very simple and effective. By adopting MATLAB/SIMULINK platform, the integrated arrangement is simulated and outcome make evident of variable speed range operation.
