Research on Three-phase PWM Rectifier with Space Vector Control

介绍了PWM整流器的工作状态,建立了整流器在旋转dq坐标系中的数学模型.引入电流前馈解耦控制,提出了基于dq坐标系的双闭环矢量控制策略.设计了双闭环电流、电压调节器PI参数,并给出了MATLAB仿真和实验结果,验证了控制策略的有效性.

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.
