Abstract: This paper introduced the aerodynamic characteristics of the wind turbine and the theories of the stator interior permanent magnet generator(SIPMG)firstly.Then maximum power point tracking(MPPT)control was realized by space vector pulse width modulation(SVPWM)rectifier which adjusted the ouput current of generator to follow the reference current.The simulation model was built in the Matlab/Simulink.The simulation results indicat that this control strategy is simple and has fast response.
