As part of a NEDO project, NICHICON CORPORATION, Osaka University, and RIKEN have developed a power conversion module capable of stable high-frequency operation using the next-generation semiconductor silicon carbide (SiC) which is expected to help realize energy conservation by enabling the miniaturization of equipment and other advances. They succeeded in demonstrating the power conversion module’s capabilities by using it in the accelerator power supply for the X-ray free electron laser SACLA at the Super Photon ring-8GeV (SPring-8) synchrotron radiation facility, which requires a power supply capable of high-precision and high-stability operation.

Going forward, NICHICON CORPORATION will proceed in utilizing this technology for advanced medical accelerator power supplies, V2H (Vehicle to Home) applications where electricity is supplied from electric vehicles to general households, and power storage systems for public and industrial use. In addition, Osaka University, will lead efforts to promote the practical application and dissemination of power conversion modules using the next-generation semiconductor SiC by developing guidelines for issues such as reliability assessment methods and participating in standardization activities in Japan and overseas.
