What does UPS stands for?

Provides continuous power supply in the event of power interruption

effectively switches from utility power to its own power source almost instantaneously

is continuouslyconnected to the protected load, draws energy from its reserves, usually stored inlead-acid batteries ,converting it to AC power.

Converts AC to DC, but the DC output is varying.

smooths the DC from varying greatly to a small ripple.

eliminates ripple by setting DC output to a fixed voltage
