Fast DC EV Charging: Common Topologies and Power Devices Used in the System

The role of DC Fast charging (DCFC) is clear in removing barriers to EV adoption. The need for shorter charging times has resulted in higher power EV fast charging approaches 400 kW entering the market. In this paper, we will discuss an overview of typical power converter topologies and power devices for the AC−DC and the DC−DC used in fast DC EV charging.
