This paper proposes a large scale wind energy conversion system comprising a direct driven PMSG connected to the grid through a power electronic interface. The variable voltage variable frequency output from the wind generator is rectified, boosted and converted in to a fixed voltage fixed frequency output. The boost chopper maintains a constant DC at the inverter terminals. The modulation index of the inverter is adjusted to extract maximum power from the wind. The system components such as wind turbine, PMSG, power electronic interface are modeled in MATLAB/SIMULINK. The performance of the system is investigated for different wind velocities. The effect of duty ratio and modulation index is studied and the results are presented.
