Valeo and ROHM team up on next generation power electronics

Automotive company Valeo and ROHM Semiconductor are collaborating on proposing and optimizing cost/performance of the next generation of power modules for electric motor inverters using their combined expertise in power electronics management. As a first step, ROHM will provide its 2-in-1 Silicon Carbide (SiC) molded module TRCDRIVE pack™ to Valeo for future powertrain offerings.

Valeo is broadening access to efficient, electrified mobility across various vehicle types and markets, covering ebikes and passenger cars through to eTrucks. By combining its expertise in mechatronics, thermal management and software development with ROHM’s power modules, Valeo aims to drive power electronics forward, contributing to the performance, efficiency, and decarbonization of automotive systems worldwide.

Valeo and ROHM have been collaborating since 2022, initially focusing on technical exchanges aimed at improving the performance and efficiency of the motor inverter — especially in electric vehicles and plug-in hybrids. By refining power electronics, both companies aim to offer optimized cost/performance by delivering higher energy efficiency, reducing heat generation thanks to an optimized cooling and mechatronic integration, and increasing overall reliability with a SiC packaging.

“This partnership marks, for Valeo Power Division, a significant step forward in delivering advanced and high-efficient power electronics,” says Xavier DUPONT, Valeo Power Division CEO. “Together, we aim to set new industry standards for high voltage inverters and accelerate the transition towards more efficient and affordable electric mobility.”

“ROHM’s TRCDRIVE pack™ provides high power density, leading to an improved power efficiency. Together, we contribute to the development of highly efficient powertrains by fostering the collaboration with Valeo,” says Wolfram HARNACK, President ROHM Semiconductor GmbH.

These  evolutions in power electronics are all essential to supporting the growing demand for longer range, faster charging capabilities and, overall, a high performance and an affordable inverter for BEVs and PHEVs.

Valeo will start supplying a first series project in early 2026. Valeo and ROHM will contribute to the improvement of efficiency and downsizing of Valeo’s next generation of xEV inverters.

TRCDRIVE pack™ is a SiC molded module developed for traction inverter drives that features high power density and a unique terminal configuration — solving the key challenges of traction inverters in terms of miniaturization, higher efficiency, and fewer person-hours. Because SiC enables low-loss power conversion under high voltage conditions, combining Valeo’s component technology, casing design and thermal management expertise  with ROHM’s power module creates a synergistic effect.
