Expansion of Application of SiC Devices for Power Electronics Products

  • Business Groups & Production Technology Groups
  • Energy Solution
  • Electronic Devices
  • Energy Saving
  • Miniaturization and weight-savings for installations utilizing SiC devices
  • Enhanced efficiency for installations utilizing SiC devices
  • Enhanced withstand voltage for installations utilizing SiC devices

We are developing power electronics products that utilize the features of SiC diodes and SiC transistors capable of high-speed switching and lower loss.

These developments have contributed to expanding the scope of SiC device application to include motor drive inverters, mega solar power conditioning sub-systems and the drive systems of Shinkansen trains (bullet trains). As a new applied product, we have developed a waterproof and dustproof type SiC mounted environmentally resistant inverter prototype that achieves low loss without the need of being installed inside a dedicated panel.

Furthermore, SiC devices can also support higher withstand voltages, and we are currently developing a technology for applying a 13 kV device to distribution systems.
