The problem
The problem
Sintered SiC modules show complex, non-monotonic degradation due to wire-bond lift-off, making health estimation harder than in conventional solder-based modules.
The solution
The solution
A lightweight physics-informed framework combines cumulative damage features, monotonicity constraints, and probabilistic uncertainty estimation.
Performance impact
Performance impact
The approach reduces lifetime-fraction estimation error by up to ~60% versus the reference baseline, with strong cross-validation stability.
The proof
The proof
It was validated on an industrial Infineon power-cycling dataset across multiple operating conditions and SiC modules.
