Silicon Carbide Power Module Integration for Automotive Traction Inverters

Nexperia B.V. and Semikron Danfoss GmbH have signed a Memorandum of Understanding to collaborate on silicon carbide-based power modules designed for automotive traction inverter applications. This cooperative effort integrates semiconductor manufacturing with advanced power electronic packaging to support power density and efficiency requirements in electric drivetrain systems.

Strategic Cooperation and Industry Challenges
The automotive industry requires electric vehicle powertrains with higher efficiency, reduced thermal losses, and lower system weight. Silicon carbide technology addresses these needs by operating at higher switching frequencies and temperatures compared to traditional silicon-based alternatives. To optimize these semiconductor properties, co-design between the chip architecture and the physical module enclosure is necessary. Nexperia brings its wide bandgap semiconductor technology to the partnership, while Semikron Danfoss provides power module packaging and integration expertise. This complementary value chain integration allows both entities to align semiconductor performance directly with structural and thermal management constraints.

Technical Alignment and System Architecture
The technical scope focuses on developing scalable digital infrastructure and power electronics for next-generation electric vehicles. In traction inverters, power modules convert direct current from the vehicle battery into alternating current to drive the electric motor. By employing early-stage co-design and joint engineering approaches, the companies aim to optimize the interfaces between the silicon carbide dies and the module substrate. This minimizes parasitic inductance, enhances thermal dissipation, and ensures structural reliability under cyclic automotive loads. The resulting modular architectures are intended to offer scalable power ratings to match diverse vehicle drivetrain specifications.

Strategic Rationale
"By combining advanced semiconductor technology from Nexperia with our module expertise, we see strong potential to achieve more together than either could alone. We look forward to exploring how this collaboration can create additional value for our customers in the rapidly evolving electric vehicle market." — Carsten Götte, SVP Semikron Danfoss Automotive Power Modules Division

"Strong partnerships are essential to unlocking the full potential of wide bandgap technologies, including SiC and GaN. With our continued R&D investments and strong focus on early-stage collaboration, we actively drive the alignment of semiconductor and system requirements from the outset. We are excited to explore how this partnership with Semikron Danfoss, a global leader in power electronics, can advance our module offering." — Edoardo Merli, SVP and Head of Business Group Wide Bandgap, IGBT & Modules (WIM), Nexperia

Implementation and Operational Impact
The joint development framework evaluates how integrated components behave under standard automotive operational profiles. Testing focuses on process stability and thermal efficiency at the system level. Integrating the power modules into existing traction inverter topologies allows automotive manufacturers to improve overall drivetrain efficiency, directly impacting vehicle range and battery utilization without increasing spatial requirements.
