UPS

UPS stands for Uninterruptible Power Supply, which is an electronic device that provides backup power to connected devices in the event of a power outage or disruption. A UPS typically consists of a battery or set of batteries that are charged when the mains power is available, and a power inverter that converts the DC battery power into AC power that can be used by connected devices.

Basic Parts of a UPS System:

Following main components of UPS:

• Rectifier/charger, which produces DC power to charge a battery and supply an inverter.

• Inverter, which produces quality electrical power free of all utility-power disturbances, notably micro-outages and that is within tolerances compatible with the requirements of sensitive electronic devices.

• Battery, which provides sufficient backup time to ensure the safety of life and property by replacing the utility as required.

• Static switch, a semi-conductor based device which transfers the load from the Inverter to the utility and back, without any interruption in the supply of power.

Function of the UPS:

• Power-off Protection.

• Voltage Stabilization.

• Surge Protection.

• High or Low Voltage Protection.

• Harmonic Distortion Protection.

• Frequency Stabilization.

• Instant Protection.

• Resists Noise.

Different Types of UPS Systems:

• Standby

• Line Interactive

• Standby Ferro

• Double Conversion On-Line

• Delta Conversion On-Line
