Since the two companies started working together back in 2015, ROHM and UAES have been collaborating and carrying out detailed technical exchanges on automotive applications utilising SiC power devices.
This partnership deepened in 2020 with the establishment of the SiC Joint Research Institute at the UAES headquarters in Shanghai, China. And in 2021 ROHM’s advanced SiC power devices and peripheral components were highly evaluated by UAES, resulting in ROHM being selected as a preferred supplier.
The close long-standing technical partnership has led to the production and adoption of numerous automotive products equipped with ROHM SiCs, such as onboard chargers and inverters for electric vehicles. SiC power devices play a crucial role in enhancing the efficiency and performance of a variety of systems, contributing to extending the cruising range and reducing battery size.
This long-term supply agreement ensures UAES sufficient access to SiC power devices to meet the growing demand for SiC-based inverter modules, which have been supplied to customers since November 2023. Going forward, both companies said that they would be looking to deepen their collaboration, contributing to technological innovation in the automotive sector by accelerating the development of cutting-edge SiC power solutions for EVs.
Commenting Guo Xiaolu, Deputy General Manager, United Automotive Electronic Systems, said, “The growing popularity of electric vehicles in the Chinese market has made the adoption and integration of power semiconductors like SiC increasingly important. ROHM is a pioneer and market leader in SiC power devices. Since 2015 we have been actively engaged in technical exchanges and highly value ROHM’s proposed solutions encompassing devices and peripheral components. Choosing ROHM as our long-term supplier of SiC chips guarantees a stable supply for future mass production.”
“UAES is at the forefront of advanced application development. To meet the need for SiC power devices that improve efficiency in the rapidly expanding electric vehicle market, ROHM has established a leading development and manufacturing system within the SiC industry,” said Tsuguki Noma, Corporate Officer and Director of the Power Device Business Unit, ROHM. “We believe that by working together, both companies can provide cutting-edge, high performance, high quality automotive applications.”
