抄録
A new uninterruptible power supply (UPS) having a flywheel for a energy storage unit is described. The UPS of the rating of 5(kW) and 100(V) 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 a half bridge configuration which can realize good input and output waveforms, high efficiency, small size and light weight.<br>Inside of the flywheel unit rotating 30, 000rpm is vacuumized to eliminate windage losses by a small vacuum pump. And the flywheel rotor is made no mechanical touch in high speed states to get as long life as 30 years. A electrical main circuit is consisted of a half bridge converter, a symmetrical half bridge inverter, and a inverter/converter to drive the fiywheel induction motor/generator. Charging or discharging control of the mechanical energy is achieved by controlling the slip frequency of the induction machine.
