Abstract :
In this paper, a new control strategy based on the 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, a 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
