A single phase high efficiency flywheel (FW) uninterruptible power supply (UPS) rating of 5kW and 200V-lmin is described. The UPS has following characteristics.<br>(1) Battery less system which makes maintenance free and long life about three times of a battery UPS.<br>(2) Simple power conversion circuit of 3 arms configuration which can realize high efficiency and small size.<br>Inside of the new flywheel unit rotating 15000rpm is vacuumized to eliminate windage losses by a zirconium getter pump. The flywheel rotor is made no mechanical touch by a pivot bearing in high speed states so as to get long life. Charging or discharging of the mechanical energy of the FW is achieved only by controlling the instantaneous slip frequency of the induction machine. The power conversion circuit is consisted of a 3 arms bridge which has a common arm of the both inverter and converter bridges. All control of the UPS is realized by simple programs on the single chip floating point DSP.
