Valeo and ROHM Collaborate on Next-Gen Power Modules for EVs

Automotive technology company Valeo and ROHM Semiconductor are collaborating to push forward the next generation of power modules for electric motor inverters through the combination of their power electronics management expertise. In the agreement, ROHM will provide Valeo with its 2-in-1 Silicon Carbide (SiC) moulded module, TRCDRIVE pack, for its future powertrain solutions.

Valeo is expanding its efforts to provide efficient, electrified mobility solutions across a range of vehicle types, from e-bikes to passenger cars, and even eTrucks. The companies combine Valeo's strengths in mechatronics, thermal management, and software development with ROHM's power modules to enhance power electronics, improving performance, efficiency, and contributing to the decarbonization of automotive systems worldwide.

The partnership between Valeo and ROHM dates back to 2022. Valeo and ROHM had signed an agreement in 2022, focusing on technical collaboration to improve the motor inverter, a critical component of EVs and PHEVs. Together, they seek optimization of cost and performance for improved energy efficiency, heat generation through advanced cooling solutions, and overall reliability through SiC packaging.

“This partnership marks, for Valeo Power Division, a significant step forward in delivering advanced and high-efficient power electronics”, said 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”.

“We are pleased to support Valeo, a renowned automotive supplier, with our power semiconductors. 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 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.
