R&D FIELDS

Assist on cutting edge product development
with Next Generation Semiconductor

Headspring carries the strength in developing high efficiency and miniaturization design with the usage of next-generation semiconductors (SiC, GaN). In addition, we have a wide range of technologies that are necessary for the development of power electronics equipment, optimizing power, electronics and control. These technologies are combined to support customer research and development.
In addition, we have modularized hardware and software as technical assets, which can be used to reduce the development man-hours for customers. Besides of able to use these modules as functional prototypes, it is possible to seamlessly use assets in future product development.
