Research on current control strategy for PWM voltage source rectifier

Luo Yao-hua

Abstract

With pulse width modulation the PWM voltage source rectifier can not only adjust the DC voltage in certain range,but also make the current in AC side of the rectifier be sinusoid and creates rectifier with high power factor.The indirect current control is an easiest way to control the current in the AC side of the recitifier among many current control ways.The law of the indirect current control was discussed based on its static model.The design of the PWM voltage source rectifier system was presented by indirect current control.The simulation result shows that the indirect current control can obtain the rectifier wich high power factor performance.
