ROHM and Geely partner on silicon carbide power devices

Power semiconductor maker ROHM and Chinese automobile manufacturer Geely Automobile Group Co Ltd have entered into a strategic partnership to develop advanced technologies in the automotive field.

The firms have been collaborating on a variety of automotive applications since 2018, when they first agreed to a technical exchange. This partnership is expected to further promote cooperation and accelerate innovation for automotive applications.

Geely is working to extend the cruising range of electric vehicles (EVs) while reducing battery costs and shortening charge times by developing high-efficiency traction inverters and onboard charging (OBC) systems that adopt ROHM’s power solutions centered on silicon carbide (SiC) power devices. At the same time, Geely says that it is committed to developing high-performance advanced driver assistance systems (ADAS) and intelligent cockpit systems using a wide range of products and solutions, including communication ICs and discrete devices.

As a first step, traction inverters equipped with ROHM’s SiC power devices are being integrated in electric vehicle platforms currently being developed by Geely.

Through the partnership, ROHM and Geely aim to contribute to sustainability by promoting the development of low-carbon technologies in the automotive industry and offering solutions for achieving greater safety and security in an increasingly mobile society.
