What is an uninterruptible power supply (UPS)?

An Uninterruptible Power Supply (UPS) is defined as a piece of electrical equipment which can be used as an immediate power source to the connected load when there is a failure in the main input power source. In a UPS, the energy is generally stored in flywheels, batteries, or super capacitors.

What is a ups & how does it work?

A UPS or uninterruptible power supply uses batteries and supercapacitors to store electrical energy and delivers this stored electrical energy when the main input power supply fails. However, a typical UPS battery can supply electrical power for a short duration. Hence, UPSs are mostly used as short run time backup power sources for small loads.
