About

Powerful and efficient traction inverters for commercial vehicles

The traction inverter in electric commercial vehicles (i.e. trucks, busses, agricultural vehicles, construction vehicles) plays an essential role in determining the vehicle's performance and efficiency. It regulates the motor's speed and torque, facilitates regenerative braking to recharge the battery, and ensures optimal power delivery. Advanced electric commercial vehicle traction inverters prioritize high efficiency, low switching losses, and thermal management to enhance the overall system performance and extend the vehicle's driving range. Infineon offers a highly scalable system solution to meet the requirements of traction inverters in heavy-duty vehicles, allowing efficiency, fast time-to-market, and optimized performance.

Technology choice (Si and SiC) in traction inverter systems

SiC-based power electronics for traction inverters in electric commercial vehicles like trucks and agricultural vehicles are accelerating rapidly. Given the WLTP mission profile, where partial load dominates, SiC demonstrates an efficiency gain of approximately 4% over its silicon counterpart. It is our belief that Si and SiC will coexist as both have their unique benefits. A Si/SiC combined solution is often considered for electric commercial vehicle traction inverters and secondary inverters, i.e., SiC is applied for rear-wheel drive to extend the range, whereas Si IGBT is used in front-wheel drive to enable cost optimization.
