A Simple Three-Phase Single-Stage AC/DC Converter with Magnetic Energy Feedback Technique for Power Factor Correction

Abstract

A simple three-phase single-stage AC/DC forward converter with transformer magnetic energy feedback technique for power factor correction is proposed. The operational principle of the proposed converter is presented. The proposed converter gives the good power factor correction, low line current harmonic distortions, and tight output voltage regulation. The prototype shows high power power factor with low line current harmonics.
