Modeling and Simulation of High Power Factor Rectifier Based on SVPWM

Jing Li

Abstract

The mathematical and Simulation model of three-phase voltage source PWM rectifier(VSR) is introduced in this paper.The double closed loop engineering design method is applied in the PWM rectifier to realize unit power factor rectifier function,by adopting the SVPWM current control method with the fixed switching frequency to track and control current.It is found in experiment that the simulation wave and experiment wave are consistent.The result shows that the mathematical model is right,and can provide a reference and assistance for the design of high power factor rectifier.
