Abstract
This paper analyzes the principle of PWM rectifier, and present a unity power factor control method of PWM rectifier. Controller used double closed-loop PI control, which inner uses three-phase input current control method controlled by unity power factor and outer controls the output DC voltage of rectifier. Voltage phase detection methods which proposed could eliminate the affection of the voltage harmonics on phase detection accuracy. The result of the simulation and experiment verify the feasibility and effectiveness of the method.
