Solid-State Transformers Boost EV Charging Efficiency

This article is part of our exclusive IEEE Journal Watch series in partnership with IEEE Xplore.

The rapid buildout of fast-charging stations for electric vehicles is testing the limits of today’s power grid. With individual chargers drawing 350 to 500 kilowatts (or more), which makes charging times for EVs now functionally equivalent to the fill-up time for a gasoline or diesel vehicle, full charging sites can reach megawatt-scale demand. That’s enough to strain medium-voltage distribution…
