Simulation for high power factor rectifier based on one-cycle control

Wang Yidong

Abstract

In order to increase the power factor of the voltage source rectifier and decrease the current harmonics of the input current,the voltage source rectifier adopted one-cycle control(OCC)technology is researched in this paper.According to the traditional methods,the one-cycle-control is a new control method of Power Factor Correction(PFC)without multiplier.The topology,working principle,control strategy of three-phase voltage source PWM rectifier are discussed.The simulation is finished by using the saber software.The simulation results show that the voltage source rectifier adopted one cycle control strategy can realize the unity power factor.
