Building a Better Electric Vehicle

Go Farther, Charge Faster, Perform Better with Wolfspeed SiC Inside.

We see a future where electric cars can go farther, charge faster and perform better – all enabled by the greater system efficiencies that you get with Silicon Carbide. You probably haven’t noticed why. That’s okay. The why is our job. Wolfspeed SiC devices are changing the EV industry from the inside out, and we’re just getting started. In the future, electric car drivers might never know what makes it possible for them to fully charge their battery during a five-minute bathroom break, or drive across the country without worrying about your next charge. But Wolfspeed SiC device engineers do, and that’s what matters.

Our team is always pushing to lead the market with EV innovations, and our new E-Series diodes and MOSFETs are no exception. With the launch of our E-Series, Wolfspeed becomes the first semiconductor manufacturer in the industry to produce a full suite of MOSFETs and diodes that are automotive qualified and capable of withstanding high-humidity environments.

Why wait to change with the market, when you could be the one leading it? Learn how to lead with Wolfspeed products by reading through the materials below and taking advantage of the tools we’ve provided to get you started.

Be sure to contact one of our experts if you’d like more information. We’re ready to help you design the future of electric vehicles.

Automotive EVs - Improve System Efficiency in Four Key Areas

Wolfspeed’s Gen3 SiC MOSFETs enable faster, more efficient charging and increase power density of the electric circuits while reducing range anxiety.

Case Study: Wolfspeed in China

Industry Challenge

China’s increasing use of motor vehicles calls for more EVs and HEVs to limit the use of fossil fuels and decrease the nation’s carbon footprint. Shinry Technologies is the leading EV and HEV power converter company for cars and buses in China. Their systems are in 1% of China’s 20 million active vehicles. All of Shinry’s power systems require devices that enable the greatest possible efficiencies for power conversion.

Wolfspeed Solution

Shinry uses Wolfspeed SiC MOSFETs to enable a 96% DC to DC power conversion efficiency rate for cars and buses. SiC MOSFETs can achieve more than three times the power density (the amount of power produced per unit volume) of typical silicon technology in standard power supply designs. This is very important in an electric vehicle, where space is limited.

System‑Level Results

Wolfspeed SiC MOSFETs enabled a 25% reduction in product size and reduced peak-power losses by more than 60% compared to the traditional silicon devices. Every product in Shinry’s showroom now contains a Wolfspeed SiC MOSFET.
