Abstract	Conventional UPS(Uninterruptible Power Supply) using batteries for assisting the source is limited by the large volume and the life-time of battery. Moreover, voltage variation caused by the sudden load variation brings the problems on UPS system output. In this paper, the battery using fuel cell which is environment-friendly alternative energy is connected on AC/DC converter for UPS to compensate the sudden load variation energy and make the stable power.
