A long life three phase flywheel (FW) uninterruptible power supply (UPS) using an electrolytic capacitor-less converter/inverter and a transformer-less isolating system rating of 200V and 5kW-lmin is described. The UPS has following characteristics.<br>(1) Electrolytic capacitor-less converter/inverter configuration which makes long life and small size.<br>(2) Transformer-less isolating system to realize small size and right weight.<br>(3) Battery less system for maintenance free and long life about 20 years.<br>The electrolytic capacitor-less converter/inverter has a small film capacitor value of 1/50 times of a conventional ones. The converter/inverter is controlled by a current and voltage follow-up method using PWM control.<br>Charging and discharging abilities of the FW energy is achieved only by controlling the instantaneous slip frequency of the induction machine.<br>The UPS has excellence test results which are obtained such as input power factor of 99.8%, small output voltage distortion of 1.03% and 93.8% efficiency at full load.
