| Abstract: | This paper introduces the operational state of the PWM rectifier and establishes the mathemati- cal model of the three-phase rectifier based on dq coordinate rotating system. By adopting the current feed decoupling control, the paper puts forward the double closed-loop vector control strategy based on dq coor- dinate. The PI parameters of current and voltage adjustor of double closed loop are designed, and the MATI.AB simulation results show it is correct and reasonable. |
