の給電が瞬断無く継続される。In this uninterruptible power supply system, a power supply device for transforming and rectifying the voltage of a commercial AC power supply is provided, and the output voltage (DC voltage) of the power supply device is applied to the battery pack to charge the battery pack. The same DC voltage is supplied to the load. When a commercial AC power source loses power or drops in voltage, the battery pack is discharged. Due to this discharge, power supply to the load is continued without interruption.
