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.
