Direct power control strategy for three-phase voltage source PWM rectifier

Xianbo Wang

Abstract

The topology and mathematical model of three-phase voltage source PWM rectifier was analyzed in this paper.Then,the direct power control based on instantaneous power estimation,direct power control without voltage sensor,virtual flux based on fixed frequency and converter output voltage calculation were analyzed,and their advantages and disadvantages were compared.On the basis of current research,the direct power control of three-phase voltage source PWM rectifier was prospected.
