Abstract- This paper describes the control and design of a Doubly Fed Induction Generator (DFIG) using back-to-back PWM converter in wind turbines. A back-to-back PWM converter is used as the excitation power supply for the DFIG wind power generation of variable speed constant frequency. The Simulink model and control strategy of converter which is connected to grid side is analyzed. The grid side converter is used to regulate the voltage of the DC link capacitor. Besides it satisfies the unity power
