Abstract: An uninterruptible power supply is having a battery, a power inverter circuit for inverting the electrical power of the battery, and a voltage control circuit. The voltage control circuit controls the power inverter circuit, so that the output voltage of the power inverter circuit is maintained at a standby voltage lower than a rated voltage under the condition of a power failure detection signal being not output from an external power supply and the output voltage of the power inverter circuit equals the rated voltage under the condition of the power failure detection signal being output from the external power supply.

Abstract: An uninterruptible power supply unit includes: an input/output terminal connected in parallel with a power supply line which supplies power from an external power supply to a load device; a battery unit whose rated voltage is a voltage equal to a voltage of the external power supply; a DC/DC converter for converting the voltage of the external power supply into an output voltage corresponding to a difference between the rated voltage of the battery unit and the charging voltage of the battery unit; a charging circuit for charging the battery unit with a voltage equal to the voltage of the external power supply added with the output voltage of the DC/DC converter; and a discharging circuit that discharges power to the load device from the battery unit through the input/output terminal in the event that the external power supply is interrupted.

Abstract: A battery indicator estimates a remaining battery capacity when a controller instructs a driving power source to start the power supply based on a battery voltage detected at a timing when the controller instructs the driving power source to start the power supply. The controller instructs the driving power source to stop the power supply after the discharge of a secondary battery by a charge-discharge circuit is ended and at a timing when a battery voltage being measured by a voltage measurer is stabilized.
