Single-Phase AC-DC PFC Converters for EV Chargers: An Overview

Power electronics converters have extended their use from renewable energy to the recent Electric Vehicles (EVs) and/or Hybrid Electric Vehicles (HEVs) market and because of this extensive use there has been a need to improve their designs to meet the demands of various applications. In this paper, different single-phase AC-DC PFC power converters topologies like the bridge, bridgeless, and totempole type used in battery chargers in EVs and HEVs have been presented. To have a wider knowledge of which topology best suites a particular specification, the advantages and drawbacks of these converters are explained. A comparison of the topologies was performed using several performance indicators.
