Design of PFC Smart Charger for Electric Vehicle Application

R. Poornima, S. Gowtham

Abstract: In this paper, a new three-phase power-factor correction (PFC) scheme is proposed using two single-phase PFC modules. . Two standard single-phase PFC modules are then employed to process the two phase power to dc output. Split inductors and diodes are employed to limit interaction between the two PFC stages. The performance of the proposed PFC rectifier was evaluated on an experimental 1.3-kW universal-line PFC prototype. In addition, a detailed analytical model for this topology is presented, enabling the calculation of the converter power losses and efficiency. These study results have been organized and published as several technical papers during the course of this project. In this technical report, the cumulative interleaved coupled induct or DC-DC converter studies are summarized.
