ROHM and UAES sign SiC power device agreement
ROHM and United Automotive Electronic Systems Co., Ltd., (UAES), a leading Tier 1 automotive supplier in China, have recently entered into a long-term supply agreement for SiC power devices.
ROHM and UAES have been collaborating and carrying out detailed technical exchanges on automotive applications utilizing SiC power devices. This partnership deepened in 2020 with the establishment of the SiC Joint Research Institute at the UAES headquarters in Shanghai, China. In 2021 UAES selected ROHM as its preferred supplier for advanced silicon carbide power devices and peripheral components.
The close long-standing technical partnership has led to the production and adoption of numerous automotive products equipped with ROHM silicon carbide products, 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 will deepen their collaboration, contributing to technological innovation in the automotive sector by accelerating the development of cutting-edge silicon carbide power technology for EVs.
Guo Xiaolu, Deputy General Manager, United Automotive Electronic Systems Co., Ltd., commented, ‘The growing popularity of electric vehicles in the Chinese market has made the adoption and integration of power semiconductors like SiC increasingly important. ROHM, a world-renowned semiconductor manufacturer, is a pioneer and market leader in SiC power devices. Since 2015 we have been actively engaged in technical exchanges. Choosing ROHM as our long-term supplier of SiC chips guarantees a stable supply for future mass production.’
Tsuguki Noma, Corporate Officer and Director of the Power Device Business Unit, ROHM said, ’We have signed a long-term supply agreement with UAES, a valued partner with whom we have built a strong cooperative relationship over the years. As a leading Tier 1 manufacturer in China, 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. We believe that by working together, both companies can provide cutting-edge, high performance, high quality automotive applications.’
