Abstract
Examples disclose an uninterruptible power supply comprising an integrated circuit. The integrated circuit comprises a charger to charge a battery and an inverter to deliver output power from the battery to a load. The integrated circuit further comprises an active filter to reduce input current to the uninterruptible power supply by compensating a power factor corresponding to input power.
Claims15
An uninterruptible power supply comprising:
- an integrated circuit further comprising:
- a charger, coupled to an input power and a battery, to charge the battery;
- an inverter, coupled to the battery and a load, to deliver output power from the battery to the load;
- and
- an active filter to reduce input current to the uninterruptible power supply by compensating a power factor corresponding to the input power.
A non-transitory machine-readable storage medium encoded with instructions executable by a processor of a computing device, the storage medium comprising instructions to:
- receive input power, by a charger, to charge a battery within an uninterruptible power supply;
- deliver output power, by an inverter coupled to the battery, to a load;
- and
- reduce input current to the uninterruptible power supply by compensating a power factor corresponding to the input power by an active filter, wherein the charger, the inverter, and the active filter are integrated on a circuit within the uninterruptible power supply and are mutually inclusive.
A method, executable by an uninterruptible power supply, comprising:
- receiving, by a charger, an input power to charge a battery;
- delivering, by an inverter, output power from the battery to a load;
- and
- compensating, by the active filter, a power factor corresponding to the input power to reduce input current to the uninterruptible power supply, wherein the charger, the inverter, and the active filter are mutually inclusive to each other.
