A Simulation Research on Three-Phase Voltage Source Rectifier Based on Double Closed-Loop Feedforward Decoupling Control

The system model of the three-Phase VSR under the three-phase static coordinate system is given. From it, the mathematical model under the rotary coordinate system is derived. Then, the feed forward decoupling control method is introduced to control the three-phase VSR. The simulation model of the system discussed in the paper is established in the Simulink environment of the MATLAB software. The simulation results show that the PWM Rectifier under the feed-forward decoupling control method has fast dynamic response and good performance in disturbance rejection of the load.
