Valeo & ROHM Semiconductor co-develop the next generation of power electronics

Views: 3200

Valeo, a leading automotive technology company, and ROHM Semiconductor, a major semiconductor and electronic component manufacturer, collaborate to propose and optimize 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 solutions.

Valeo is broadening 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 Valeos expertise in mechatronics, thermal management and software development with ROHMs power modules, Valeo drives the power electronics solution forward, contributing to the performance, efficiency, and decarbonization of automotive systems worldwide.

Valeo and ROHM have been collaborating since2022, initially focusing 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 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.

We are pleased to support Valeo, a renowned automotive supplier, with our power semiconductors. ROHMs 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 early2026. Valeo and ROHM will contribute to the improvement of efficiency and downsizing of Valeos next generation of xEV inverters.
