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

The electric vehicle (EV) market is expected to jump from 3.2 million units in 2019 to nearly 27 million units by the year 2030. Major players in this industry are expected to invest over $350 billion in the near future to grow the electric vehicle market.

Wolfspeed SiC Power Devices for EV On-Board Battery Charger — Wolfspeed's 6.6 kW High Power Density Bi-Directional EV On-Board Charger Reference Design

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.

Wolfspeed SiC Power Components for On-Board Battery Chargers — On-Board Charger (OBC)

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.

System Cost Savings

Wolfspeed Silicon Carbide also enables 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.

Wolfspeed Silicon Carbide Products Built to Support OBCs

Wolfspeed products represent the culmination of years of experience and expertise, where quality meets innovation to help bring your design forward. Wolfspeed’s 1200V and 650V Silicon Carbide MOSFETs offer the industry’s lowest drain-to-source on-resistances, enabling up to 50% higher power density, which means more power to charge your battery with a smaller and lighter charger.
