Comparative Study of Single-phase Power Factor Correction Topologies for Electric Vehicle Battery Charger Based on Boost Converter

Nowadays electric vehicles (EVs) are the most popular due to their cost-effectiveness and as an alternative to traditional petroleum fuel-based vehicles. When EV is charged from the utility grid conventional AC-DC converter act as a nonlinear load drawing peaky current from a supply and results in a very poor input power factor. The converter present at the input AC side which converts alternating current (AC) into direct current (DC), a crucial part of an electric car battery charging system, must have high efficiency. The topologies for use at the ac input side to convert ac into dc for EV battery charging are evaluated in this paper. The focus is on boost converter-based power factor correction converters, which provide excellent efficiency, good power factor, and affordable pricing. Traditional boost power factor correction converter, interleaved boost power factor correction converter, and bridgeless totem pole boost power factor correction converter are the topologies under investigation. The performance of all these topologies is simulated using Matlab/Simulink. All converters give the output of 400 V DC from a universal ac input voltage with a Total Harmonic Distortion (THD) percentage level that satisfies the IEEE Standards are provided with their simulation results.
