Abstract :
In this paper, two control laws based respectively on hysteresis and pulse-width-modulation (PWM) techniques are applied on a unity-power-factor current-injection-based three-phase rectifier. A theoretical analysis is carried out in order to evaluate the performance of each technique, in terms of the line current ripple and the switching frequency. The control detuning problem, which contributes mainly to the line current distortion, is also considered. In order to highlight the comparative study, numerical simulation is accomplished using the Power System Blockset tool of Matlab/Simulink
