As a truly global megatrend, all EV chargers need to use electrical energy in the most effective way. For every type of charge point, at every voltage, the need for highly efficient energy conversion is universal. That’s what silicon carbide brings to EV charging.
Technology developed by onsemi is defining the global EV charging infrastructure. This includes its SiC MOSFET modules, delivering power levels of 350 kW to charge EVs faster and more economically. SiC-based power modules from onsemi have been endorsed by leaders in the automotive industry. These modules are in production electric vehicles now, delivering longer ranges, higher efficiency, and faster acceleration.
Advanced discrete and modular solutions enable traction inverters to generate higher levels of torque. Efficiency here extends the range of the vehicle and the lifetime of the electrical drive train.
Integrated single side direct cooling (SSDC) power modules from onsemi, compatible with onsemi’s IGBT modules, use its second generation SiC MOSFETs to deliver higher performance and better efficiency, all with onsemi’s industry-leading quality.
