Abstract:A control method to maximizing the system output,for a small wind energy conversion system composed of a new type of brushless DC generator,is put forward£® With the aid of the method,the wind turbine torque vs£®rotate speed characters can be indirectly controlled via adjusting the machine electromagnetic torque vs£®rotate speed characters£¬and the wind turbine operation with the optimum tip-speed ratio£¨TSR£©and the maximum power point (MPP) is automatically tracked£®A method for designing the power conditioner using this control strategy is presented in detail£®A 100 W power conditioner prototype is designed and constructed£® The experimental results confirm the effectiveness of this method during maximum power tracking£®
