| Abstract: | Based on the mathematical model of three phase PWM high frequency rectifier, the theory of dual -close-loop controller and implementation of unit power factor of the supply-side rectifier in doubly-fed generation system are analyzed. A model of SVPWM rectifier is designed, and it shows the ability of bi-direction power flow and acting as a converter or an inverter with unit power factor. The simulation results show that the designed rectifier has excellent steady-state and dynamic performance. |
