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: A control unit is configured to determine success or failure of a rewrite process after end of the rewrite process, and write success or failure display data into a success or failure determination result storage area in accordance with the success or failure, and read the success or failure display data present in the success or failure determination result storage area after startup of an electronic device, and execute a control program, in lieu of carrying out the rewrite process, when it is determined that the success or failure display data indicate a success of the rewrite process.

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.
