SiC Power Module

SiC power modules are energy-saving, eco-friendly devices that offer several improvements over conventional products. They make effective use of power and resources and reduce costly power consumption while maintaining or increasing performance. For example, the switching loss in full SiC power modules integrating SiC MOSFETs and SBDs is significantly lower than in equivalently rated silicon-based IGBT modules.

In addition, unlike conventional modules, these new SiC products support high-frequency operation above 100kHz. This improves efficiency in industrial equipment such as high-frequency power supplies for induction heating and hybrid-power storage systems.

ROHM was the first in the industry to mass produce SiC power devices, which have since been adopted in a variety of fields, including industrial, automotive, railway, and consumer electronics. And due to their superior stability at high voltages, ROHM SiC power modules are used in Kurita Seisakusho high-power pulse plasma generators that deliver a reaction field up to 200kHz to better support customer requirements, a feat made possible only through SiC.
