Semiconductor manufacturer Rohm and Bosch joint venture United Automotive Electronic Systems (UAES), a Chinese Tier 1 automotive manufacturer, open a joint laboratory for SiC (silicon carbide) technology reasearches at UAES headquarters in Shanghai.

Rohm and UAES have been working together since 2015, conducting a detailed technical exchange on automotive applications with SiC power devices. After many years of technical dialogue, automotive products with SiC power semiconductors from Rohm were launched earlier this year.

The new joint laboratory for the development of mass-market automotive applications contains extensive equipment for the evaluation of devices and applications, for example onboard chargers and DC/DC converters. The companies are thus strengthening their partnership and accelerating the development of innovative power supply solutions based on SiC.

SiC power semiconductors are increasingly used in electric vehicles, infrastructure, environmental/energy and industrial equipment. These components offer significant advantages over silicon-based power devices. These include significantly lower switching and conduction losses, as well as higher temperature resistance.

Who is UAES?

UAES, a Tier 1 automotive manufacturer, was founded in 1995 as a joint venture between Robert Bosch and Zhonglian Automobile Electronics Systems Co., Ltd. (a Chinese company affiliated with SAIC). The company has since gained a large share of the Chinese market for engine control and drive systems for gas-powered vehicles. Since 2009, UAES has focused on the development of electric vehicle applications, including main inverters.
