本文介绍了一种5 kW、200 V-1 min单相高效飞轮式不间断电源。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)3臂结构的简单功率转换电路，可实现高效率和小尺寸。旋转15000 rpm的新型飞轮单元内部通过锆吸气剂泵抽真空以消除风阻损失。飞轮转子在高速状态下通过枢轴轴承没有机械接触，从而获得长寿命。FW的机械能的充电或放电仅通过控制感应电机的瞬时转差频率来实现。功率转换电路由一个三臂桥组成，该桥具有逆变器桥和转换器桥的公共臂。UPS的所有控制都是在单芯片浮点DSP上通过简单的程序实现的。
A single phase high efficiency flywheel (FW) uninterruptible power supply (UPS) rating of 5kW and 200V-lmin is described. The UPS 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 3 arms configuration which can realize high efficiency and small size.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.
