A New DPC for Three-phase PWM rectifier with unity power factor operation

Abstract

This paper, presents the performance evaluation for new methods, applied to three-phase PWM rectifier with unity power factor operation, based on virtual flux called Direct Power control (VF-DPC). The principle of this control is based on the instantaneous active and reactive power control loops. The results show the excellent advantages, particularly: nearly sinusoidal input current, regulation of input power factor to unity, low harmonic distortion of line current (THD below 5%), adjustment and stabilization of DC-link voltage (or current), reduced capacitor (or inductor) size due to the continues current.
