A multi-device front-end power factor converter for EV battery charger

Abstract

This work presents a front-end a novel boost power factor converter for on-board plug-in electric vehicle battery charger. The converter has lower passive components size such as inductor and EMI filter. In addition, low switch stress and higher efficiency can be expected. As a result, the size of charger, charging time and cost of electricity is minimized. In addition, a detailed current stress model of this topology is presented for selection of power stage components as well as for efficiency calculation. The proposed converter is simulated in Matlab/Simulink environment to demonstrate its effectiveness.
