PFC and AC-DC Conversion Converter for Electric Vehicle Application

Abstract

A new three-phase three-level single-stage power-factor corrected ac–dc converter with interleaved input has been proposed in this project. The converter operates with a single controller to regulate the output voltage and uses auxiliary windings taken from its power transformer as magnetic switches to cancel the dc bus voltage so that the input section operates like a boost converter. The proposed rectifier can produce input currents that do not have dead band regions with high PFC, operate with a continuous output current, and minimize the input electromagnetic interference filter size. The proposed converter can operate with lower peak voltage stresses across its switches and the dc bus capacitors as it is a three-level converter. It is more efficient because  it has fewer diodes in the dc bus and it has less turn-on losses. The proposed topology implemented In extension the proposed concept can be implemented for electric vehicle application by using MATLAB/SIMULATION software and the results are verified
