- Abstract
It describes the working principle of VIENNA rectifier and establishes its mathematical model. According to the operation characteristics of VIENNA rectifier, it adopts double closed-loop control of voltage and current. In order to improve the anti-interference ability of the voltage outer loop, PI control is added to the voltage outer loop to reasonably control the malpractice of output voltage instability caused by disturbance. Feed-forward decoupling control is adopted in the inner loop to realize the separate control of d-q axis current, reduce the error caused by coupling, improve the power factor and reduce reactive power. Finally, the algorithm is modeled and simulated by Matlab. The simulation results show that PI control is used in the outer loop to improve the anti-jamming ability of the system. And feed-forward decoupling control is used in the inner loop to reduce the harmonic distortion of the input current and improve the power factor.
