ROHM, with China's Tier 1 automotive manufacturer UAES
SiC-based products including OBCs and DC/DC converters
Joint establishment of a facility for evaluating sets of parts and devices


ROHM announced on the 8th that it opened a 'SiC Technology Joint Laboratory' inside the Shanghai headquarters of UAES (United Automotive Electronic Systems), a Chinese Tier 1 automotive equipment manufacturer, and held an opening ceremony last October.

Silicon carbide (SiC) power components have the advantage of lower switching and conduction losses and resistance to temperature changes compared to silicon (Si) products such as IGBTs, so their adoption is being promoted in electric vehicles, as well as in infrastructure, environment, energy, and industrial sectors.

Since 2015, the two companies have been exchanging technologies regarding the development of automotive devices equipped with SiC power components. This year, UAES products employing ROHM's SiC power components were also mass-produced.

The newly established joint laboratory has introduced facilities capable of evaluating automotive application sets, including on-board chargers (OBCs) and DC/DC converters, as well as devices for evaluating components.

"The establishment of this joint laboratory is proof of the strengthened cooperative relationship between the two companies," said Guo Xiaolu, Deputy General Manager of UAES. "In the future, we expect to be able to provide a higher level of technical support through various facilities."

Ino Kazuhide, General Manager of ROHM’s Power Components Business, stated, “Research that responds to customer needs and market trends in the growing automotive sector will be an important factor in competitiveness,” adding, “The two companies will develop SiC-centered power solutions through a joint laboratory.”
