Drive innovative traction inverter solutions
  • Automotive-qualified portfolio for various motors, generators, and power classes.
  • Highly scalable automotive power solution (frame, molded, discrete, bare die) that simplifies platform migration and reduces design work.
  • Gate drivers with slew rate control for efficient performance.
  • 32-bit microcontrollers with features like resolver interface and AI predictive maintenance.
  • Coreless current sensor scalable for the 2nd-generation HybridPACK™ Drive™ power module.
  • Evaluation kit with 30+ Infineon components to shorten development time.
Technology choice (Si and SiC) in EV traction inverter systems

SiC-based power electronics for EV inverters are advancing quickly. Under the WLTP profile, characterized by partial current loads, SiC offers about a significant 6% range gain in 800V systems compared to silicon. Both materials are expected to coexist — SiC in rear-wheel inverters for range extension and silicon in front-wheel systems for cost savings. Additionally, innovative fusion technology combining Si and SiC delivers significant cost benefits, though with a slight range reduction. Infineon leads this innovation, partnering with top automotive Tier 1 suppliers to enable the most cost-efficient EV inverters.
