A driver for a brushless dc motor (BLDCM) which is supplied by a wind generator (WG) is proposed in this paper. The proposed system uses a buck converter with high efficiency and control unit for implementation maximum power point tracking (MPPT) technique. No optimal characteristic of the WG or an anemometer for wind speed measuring is needed while the WG works is variable speed mode, whereas simplicity and reliability of the proposed system is improved, cost and mechanical tension of the WG is already reduced. Usage of available wind energy is achieved too; specifically under low wind speeds. The whole system is used in electric vehicle application. In order to evaluation of the proposed system performormance, simulation is runned by MATLAB/Simulink. The result confirms its advantages.
