Design and Simulation of Current Source Rectifier's Double Closed-Loop Control System

Aiming at how to overcome the advanced power factor because of the introduced LC filter at the AC side of three-phase current source PWM rectifier,a tri-logic PWM technology and double closed-loop control method were used.The rectifier’s simulation model was established under Matlab/Simulink environment.The simulation results indicated that the current source rectifier's AC side could run at unity power factor and the rectifier could ob-tain stable output DC current.
