Abstract

Due to the enhancement in high-speed switching semiconductor devices, the employ of three-phase PWM boost rectifier (BR) has grown to be more common in the past decade. The PWM rectifier can provide input currents without distortion and with unity power factor at the supply terminals. The description and modeling of the three-phase PWM rectifier have been analyzed using the voltage source inverter (VSI) with resistive load. The proposed control scheme in this paper has two closed loops to compute the three-phase reference currents of PWM rectifier. The first, namely dc load current loop, and the second, using dc bus voltage loop. The unity power factor and reduction of pollution harmonic is completely fulfilled with current controller that is applied linear current controller. The Simulation and experimental results verify the operational characteristics of the PWM rectifier.
