Challenge
A top-5 global EV manufacturer needed to improve traction inverter efficiency for their 800V platform to extend range by 8% while meeting ASPICE Level 2 and functional safety requirements.
Solution
CoreWin provided ONSEMI 1200V Gen 2 SiC MOSFETs in a pin-to-pin compatible package to the existing IGBT module footprint. Our FAE team supported full thermal simulation, gate drive design review, and ASPICE-aligned documentation.
Key Outcomes
Traction inverter peak efficiency: 99.0% (up from 96.2%)
Driving range extended by 8.3% on WLTP cycle
Thermal management cost reduced by 22%
Full ASPICE Level 2 compliance achieved
