Valeo and Rohm to co-develop next gen power electronics
Valeo, an automotive technology company, and Rohm Semiconductor are collaborating to optimise 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 SiC moulded module TRCDRIVE pack to Valeo for future powertrain solutions. Rohm developed TRCDRIVE specifically for traction inverter drives. It features high power density and a unique terminal configuration to solve challenges in terms of miniaturisation, higher efficiency, and fewer person-hours.
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 Valeo’s 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 decarbonisation of automotive systems.
Valeo and Rohm have been collaborating since 2022, 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 optimised cost/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," 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. 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.
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.
