This paper presents a system in which a wind Permanent Magnet Synchronous Generator feeds an isolated load through a Boost Converter. The output voltage and frequency of the PMSG is variable in nature due to non uniform wind velocities. The fluctuating output is rectified and kept constant by means of a boost converter. A fuzzy logic controller is designed to set the duty ratio of the boost converter is varied to maintain a constant DC output voltage. Also to choose the moment to charge/discharge the battery and the moment to dissipate excess energy in a resistance.This converter output is converted to three phase ac using a three phase PWM inverter, which employs hysteresis current control to control the output voltage The power converters together with independent control systems can effectively improve the output voltage and frequency of the wind PMSG feeding an isolated load. The model has been demonstrated using MATLAB Simulink based simulations.
