January 1, 2025 /SemiMedia/ — ROHM Semiconductor and Valeo have partnered to develop next-generation power electronics for electric vehicles (EVs), marking a significant advancement in the automotive industry’s electrification efforts. As leaders in semiconductor and automotive technology, the two companies are working together to push the boundaries of electric mobility.

The collaboration focuses on creating revolutionary powertrain systems, beginning with ROHM’s groundbreaking 2-in-1 silicon carbide (SiC) module, the TRCDRIVE pack™. This high-performance module will be integrated into Valeo's upcoming power systems, enhancing the efficiency and compactness of electric motor inverters—critical components at the heart of every electric drive system, from e-bikes to heavy-duty electric trucks.

Valeo aims to make electric mobility more accessible while driving the development of environmentally friendly technologies. ROHM’s SiC module plays a crucial role in improving performance, combining Valeo’s expertise in mechatronics and software development with ROHM’s superior efficiency in power modules. This collaboration is a key step in advancing the automotive industry’s decarbonization efforts.


“Partnering with Valeo gives us the opportunity to co-develop efficient drive solutions,” said Wolfram Harnack, President of ROHM Semiconductor GmbH.


“We aim to set new industrial standards for high-voltage inverters and accelerate the transition to more efficient and affordable electric mobility,” said Xavier Dupont, CEO of Valeo Power Division.

Since 2022, ROHM and Valeo have been working closely together to optimize inverter performance for electric vehicles (EVs) and plug-in hybrid electric vehicles (PHEVs). Their shared goal is higher energy efficiency, better cooling, and reduced heat generation. The integration of SiC technology, along with a compact casing, results in an inverter that is not only more durable but also more cost-effective.


“This partnership is paving the way for the future of electric vehicles, helping us set new standards for high-voltage inverters that lead to more efficient and affordable electric drivetrains, ” Xavier Dupont emphasized.

The innovation resulting from this collaboration is critical to meeting the growing demand for longer driving ranges, faster charging speeds, and cost-effective, high-performance inverters. Valeo plans to begin mass production of its first project in 2026, a milestone that could reshape the future of electric vehicles.

With ROHM’s TRCDRIVE pack™ technology and Valeo’s engineering expertise, the solution not only aims to enhance the efficiency of electric vehicles but also contribute to a low-carbon society.
