High Dynamic Control a PWM Rectifier under Unbalanced Voltage Supply with Deadbeat Current Controllers

Abstract

In this paper, a control scheme of a three phase PWM boost rectifier using two parallel current deadbeat controllers is proposed. An unbalanced three-phase system produces the second order oscillation of the main frequency in DC link voltage. Two separated positive and negative sequence synchronous reference frames are applied. By using a notch filter to… (More)
