White Paper Overview 

DC Fast Charging plays a crucial role in removing barriers to EV adoption. Three−phase Power Factor Correction (PFC) topologies are key for efficiently powering the fast DC charging and maximizing the advantages of SiC power semiconductors. This paper discusses power converter topologies and AC-DC and DC-DC power devices used in fast DC EV charging.
