When designing modern OBC systems, engineers are targeting to maximize efficiency, power density, and reliability while minimizing cost and complexity. Meeting the demanding requirements of today’s EV manufacturers takes world-class technology backed by world-class expertise. Wolfspeed Silicon Carbide MOSFETs and diodes along with our team of power systems experts enable customers to design optimized OBCs in the fastest amount of time.

All EV powertrains propel their host vehicle, but exactly how that’s accomplished is up to the designer. He or she seeks to devise an elegant system which fluidly induces all the moving parts to do their jobs faster, using less power, at a lower price point. Many are designing around Wolfspeed’s 1200V Silicon Carbide MOSFET for its capability to handle high current with the industry’s lowest drain-source on resistance, which increases the distance consumers can drive on a single charge.

Wolfspeed’s Silicon Carbide delivers the higher voltages and power levels needed to power today’s EV charging infrastructure. Compared to a silicon system, a Silicon Carbide fast DC charging solution can deliver 33% more power in 25% the area, and the 50% lower losses won’t run up your electric bill.

An EV’s diverse systems are powered by diverse voltages – propulsion, HVAC, window lifts, lighting inside and out, infotainment and seat belt sensors are just some of a very long list. The on-board DC/DC unit must convert and portion out the correct voltage to each in real time, enabling all systems to work as one. Silicon Carbide devices ensure this process transpires faster, more reliably and with greater efficiency than any silicon-based solution.
