The World of Transportation Is Changing. Can Your Power Solutions Keep Up?
A Shifting Landscape
The automotive industry is changing before our eyes. As demand for energy efficiency grows, car manufacturers are increasingly turning toward electric vehicles (EVs) to meet these changing conditions. What used to be a rarity — the fully electric or hybrid electric vehicle — can now be found on just about every street corner across the globe. The increase in EVs over the past five years in particular is stunning… but can our infrastructure keep up?
A Global Phenomenon
Encouraged by increasingly strict environmental regulations and enabled by innovations in technology, car manufacturers like Tesla, BMW, and Porsche are pushing the limits of what was thought possible with EVs. The Volkswagen group alone is expected to release 70 new EV models in the next 10 years.
Still, many consumers are approaching these new transportation solutions with hesitation.
WHY?
The need for fast-charging solutions.
Consumers still have anxiety over the range of EVs and expect them to charge as quickly as you would fill a gas-powered car with fuel — in less than 15 minutes.
Countries across the globe are making significant changes to their electric grids to keep up with the rising demand for electric vehicles and the corresponding energy consumption changes that come with it. Already, China has made significant progress toward building a reliable DC power infrastructure that can support fast-charging capabilities. Europe is not far behind.
China and Europe Leading the Charge
The United States is lagging behind. But there is a solution…
What about the United States?
A Next-Gen Charging Infrastructure — Fueled by Wolfspeed’s Silicon Carbide Solutions
The demands of a fast-charging infrastructure are significant. Modern solutions must meet these requirements:
150 kW max for single car charging Wide working range (300 V to 825 V) Robust for dirty/wet environments Withstand global weather conditions
So how do
solutions fit in?
WOLFSPEED's SILICON CARBIDE (SiC)
Furthermore, different customers of fast-charging stations will have different priorities:
Rugged Connected Flexible/Universal High-Efficiency Affordable Small High Reliable Easily Installed

EV Owner
Wolfspeed’s SiC solutions help create smaller, lower-cost, energy-efficient chargers. This is achieved by simplifying the overall charger design. With higher power conversion capability, faster switching speeds, and improved thermal performance, SiC is an ideal material to meet the extreme power demands of modern fast-charging stations.
Wolfspeed SiC in Action
Fast chargers bypass vehicle on-board chargers (OBCs) for rapid direct battery charging. This allows batteries to be charged in just 30 minutes versus 4+ hours from OBCs. But the demands of these systems are significant. Off-board charging stations need:
WOLFSPEED
is up to the challenge.
SiC
Imagine an EV battery-charging station providing an 80-kW to 350-kW charge. By using SiC MOSFETs and diodes from Wolfspeed, the design will minimize the size and weight and cost of the charging station while maintaining a 30-minute-or-less charge time.
BY USING SiC, THIS CHARGING STATION WILL HAVE:
THE HIGHEST EFFICIENCY
IMPROVED POWER DENSITY
HIGH RUGGEDNESS AND RELIABILITY
BIDIRECTIONAL ENERGY FLOW
REDUCED SYSTEM COST
By using SiC, this charging station will have:
Up to 30% lower losses 2× to 3× faster switching speed 65% increase in power density 30% fewer components Lower overall system cost
Why SiC… and Why Wolfspeed?
power solutions help build fast-charging stations that are:
