Abstract :
Recently the electric double-layer capacitor (EDLC) which is rapidly charged and discharged and offers long life, maintenance-free, has been developed as a new energy storage element. Therefore, we developed the uninterruptible power supply system utilizing EDLC. This paper describes the outline of this system and the instantaneous voltage sag compensation result.
