AC filter capacitors are a limiting factor for reliability of power conversion systems in network power and alternative energy applications. Conventional capacitors with pressure interrupters or fuses often fail catastrophically with significant collateral damage. A next generation annular form factor dry-film capacitor has been developed to eliminate catastrophic failures using proprietary end connection and segmentation technology. By […]

A flywheel energy storage system (FESS) is a power storage device that stores electrical power by rotating energy. The FESS we develop has a large capacity to charge electrical power from a solar power system and other renewable generators and discharge the power to power networks. A superconducting magnetic bearing developed by Furukawa Electric and Railway […]
