On-Board Charger
Wolfspeed understands the technological challenges that EVs present for engineers, especially when it comes to power and EV charging solutions.
Ready to Support a Booming Industry
Wolfspeed’s silicon carbide (SiC) products enable OBCs with bidirectional energy-transferring capabilities. This means automotive manufacturers can design systems that can both receive energy from the grid and give it back, helping to stabilize the electrical grids of the future, or even power an owner’s critical home systems during a power outage.
A Charging Problem
While electric vehicles are becoming more commonplace, many consumers continue to have concerns about range and charging capabilities. For decades, the consumer driving experience has been powered by fossil fuels, and refueling meant a quick stop at the gas station to top off the tank. The prospect of a lengthy charging process to keep your car traveling down the road or of being limited to using a stand-alone charging station are massive deterrents.
Enter On-Board Battery Chargers
On-board battery chargers are the key to keeping EVs powered—they take AC current from the car owner’s home and convert it to DC power to recharge the battery. They are also often capable of harvesting kinetic energy from the vehicle itself to provide additional charge when braking. But traditional silicon has made these systems very limited in both their output, size and speed.
A New Level of OBC Capability, Powered by Wolfspeed Silicon Carbide
Traditional silicon has limitations, particularly when it comes to high-power applications like those of on-board charging systems. But Wolfspeed Silicon Carbide (SiC) is uniquely capable of handling higher voltages and currents, taking on even the most challenging of power applications.
