An uninterruptible power supply (10) has rechargeable batteries (1) having a voltage specification of 60V or less, an AC/DC converter (2) that converts power input from an external commercial power source (50) to DC and supplies it to the input power supply lines (23), a DC/DC step-down converter (3) that steps-down the AC/DC converter (2) output voltage to the rechargeable battery (1) charging voltage, a DC/DC boost converter (4) that steps-up the rechargeable battery (1) voltage and supplies it to the input power supply lines (23) during power outage, and a charging and discharging control circuit (5) that detects commercial power source (50) outage and switches the DC/DC boost converter (4) to the operating state.",
