Modeling and analysis of a three-phase unity power factor current injection rectifier using one loop control strategy

摘要

In this paper, a new control strategy based on Pulse-Width-Modulation (PWM) control technique and using a single feedback current loop is proposed. The control scheme is applied to a particular three-phase unity power factor (UPF) current injection AC-DC converter. For this purpose, dynamical model of the converter is developed using the state-space averaging method. Simulation results are used to validate the theoretical approach carried out through the paper.
