描述了一种具有用于能量存储单元的飞轮的新型不间断电源（UPS）。额定功率为5（kW）和100（V）的UPS具有以下特点：（1）无电池系统，免维护，寿命长，约为电池UPS的三倍。(2)半桥结构的简单功率变换电路，可实现良好的输入输出波形，效率高，体积小，重量轻。转速为30，000 rpm的飞轮单元内部通过小型真空泵抽真空，以消除风阻损失。飞轮转子在高速状态下没有机械接触，寿命长达30年。电气主电路由半桥变换器、对称半桥逆变器和逆变器/变换器组成，以驱动飞轮感应电动机/发电机。通过控制感应电机的转差频率来实现机械能的充放电控制。
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:(1) Battery less system which makes maintenance free and long life about three times of a battery UPS.(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.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.
