The three general categories of modern UPS systems are on-line, line-interactive and standby: • An online UPS uses a "double conversion" method of accepting AC input, to DC for passing through the (or battery strings), then inverting back to 120 V/230 V AC for powering the protected equipment.

An uninterruptible power supply (UPS) or uninterruptible power source is an electrical apparatus that provides emergency power to a when the input power source or fails. A UPS differs from an auxiliary or or in that it will provide near-instantaneous protection from input power interruptions, by supplying energy stored in batteri.

What is an uninterruptible power supply (UPS)?
An uninterruptible power supply (UPS) or uninterruptible power source is an electrical apparatus that provides emergency power to a load when the input power source or mains power fails.
What is a dynamic uninterruptible power supply?
For large power units, dynamic uninterruptible power supplies (DUPS) are sometimes used. A synchronous motor/alternator is connected on the mains via a choke. Energy is stored in a flywheel. When the mains power fails, an eddy-current regulation maintains the power on the load as long as the flywheel's energy is not exhausted.
Why is continuity of power supply important?
While continuity of power supply is an important functionality, it is not the only one: for example, a UPS system can also filter voltage spikes, voltage drops, or noise and ensures a constant frequency or guarantees a certain power quality.
What happens if a power ups voltage is distorted?
The voltage distortion then can cause problems in all electrical equipment connected to that power source, including the UPS itself. It will also cause more power to be lost in the wiring supplying power to the UPS due to the spikes in current flow.
