ROHM's 'SiC Power Device' Installed in OBC for Chinese Electric Vehicles
Applied to Chinese Tier 1 company UAES cars from October
Achieved 95.7% unit efficiency and reduced power loss by 20%
ROHM's SiC power devices (SiC MOSFETs) have been adopted for the electric vehicle OBC (On Board Charger) of UAES, a Chinese comprehensive automotive equipment Tier 1 company.
The OBC adopted this time achieved 1% higher efficiency (95.7% efficiency) per unit compared to existing products, and reduced power loss by approximately 20%.

SiC power devices are semiconductors that can achieve dramatic loss reduction compared to Si power devices such as IGBTs, and are used in social infrastructure, environment/energy, and industrial equipment fields including electric vehicles.
ROHM began mass production of SiC MOSFETs for the first time in the world in 2010, and has continued to provide automotive-related products by taking the lead in the automotive market in 2012.
ROHM, which has a high market share in OBCs for rapid charging of electric vehicles, is also accelerating its adoption in motors and inverters.
ROHM will design OBS for UAES automobile maker in October.
