【Abstract】 The doubly-fed wind power generation system uses two-level dual pulse width modulation(PWM) converter in which the grid-side of the PWM converter is used to control the input current characteristics of the PWM converter and direct current bus voltage.And two control strategies of the rotor side converter are analyzed by the mathematical model of the doubly-fed induction generator(DFIG).The experiment verify the control strategy of the dual PWM converter.更多还原
