Valeo and ROHM to create next generation of power modules

As a first step, ROHM will provide its 2-in-1 Silicon Carbide (SiC) molded module TRCDRIVE pack to Valeo for future powertrain solutions. 

Valeo is widening access to efficient, electrified mobility across various vehicle types and markets from the smallest one (ebikes), through the mainstream (passenger cars) to the biggest one (eTrucks). By combining Valeo’s expertise in mechatronics, thermal management and software development with ROHM’s power modules, Valeo drives the power electronics solution forward, contributing to the performance, efficiency, and decarbonisation of automotive systems worldwide.

Valeo and ROHM have been in collaboration since 2022, which initially focused on technical exchanges aimed at improving the performance and efficiency of the motor inverter – a key component in the propulsion systems of electric vehicles (EVs) and plug-in hybrids (PHEVs).

By refining power electronics, both companies aim to offer both optimised cost and performance by delivering higher energy efficiency, reducing heat generation thanks to an optimised 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," said Xavier DUPONT, CEO, Valeo Power Division. "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,” added Wolfram HARNACK, President, ROHM Semiconductor.

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.
