Abstract
An uninterruptible power supply configured to automatically detect a load level and automatically power off and disable power supply or automatically power on and enable the power supply based on a detected load level, so that energy of a backup source of the uninterruptible power supply is not wasted and a life-cycle of the uninterruptible power supply is extended.
Claims17
An uninterruptible power supply having a standby mode and a backup mode, the uninterruptible power supply comprising:
- an input unit configured to receive AC input power from an AC source;
- a control unit coupled to the input unit;
- and
- an output unit coupled to the control unit and configured to supply AC output power to a load;
- wherein the control unit is configured to:
- automatically detect a load level measurement;
- determine whether the uninterruptible power supply is operating in the backup mode or the standby mode based on whether power is being supplied to a load from the uninterruptible power supply, wherein the backup mode is determined when the uninterruptible power supply supplies power to the load and the standby mode is determined when the uninterruptable power supply does not supply the power to the load;
- automatically power off to disable the power supplies to the load when operating in the backup mode and when the detected load level measurement is less than a predetermined value;
- and
- automatically power on and start supplying power to the load according to the detected load level measurement.

A method for enabling an uninterruptible power supply to save energy, the method comprising:
- supplying AC output power to a load;
- automatically detecting a load level measurement;
- determining whether the uninterruptible power supply is operating in the backup mode or the standby mode based on whether AC output power is being supplied to a load from the uninterruptible power supply, wherein the backup mode is determined when the uninterruptible power supply supplies AC output power to the load and the standby mode is determined when the uninterruptable power supply does not supply the AC output power to the load;
- automatically powering off the uninterruptible power supply and disabling power supply to the load when the uninterruptible power supply is in the backup mode and the load level measurement is less than a predetermined value;
- and
- automatically powering on the uninterruptible power supply and enabling the power supply to the load when the uninterruptible power supply is in the standby mode and the load level measurement is above the predetermined value.
