PROJECT TITLE :

A Bridgeless Totem-pole Interleaved PFCConverter for Plug-In Electric Vehicles - 2016

ABSTRACT:

This paper proposes a bidirectional bridgeless totem-pole interleaved power-factor-correction (PFC) converter using SiC MOSFETs as the front-finish stage of an onboard charger for plug-in electrical vehicles (PEVs). The proposed converter provides bidirectional operation enabling each grid-to-vehicle (G2V) charging and vehicle-to-grid (V2G) ancillary services. The converter is suitable for efficient G2V V2G onboard charging thanks to its superiorities in terms of bidirectional operation, smaller current ripple, lower EMI, lower conduction losses and switching losses. A three.3kW PFC converter is intended and developed, using Silicon-Carbide MOSFETs with fast recovery body diodes, for validation of and V2G operating modes. Utilizing SiC MOSFETs permits continuous current mode (CCM) operation of the totem-pole PFC converter in high-power applications. The converter is capable of changing 85Vac-265Vac line voltages into a regulated dc voltage within the vary of 300V to 600V. The most potency of converter reaches up to ninety nine.a pair of% with 0.ninety nine power issue.
