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.
UPS Definition: A UPS (Uninterruptible Power Supply) is defined as a device that provides immediate power during a main power failure. Energy Storage: UPS systems use batteries, flywheels, or supercapacitors to store energy for use during power interruptions.
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.
Typically, according to different working principles, UPS power supply covers standby (offline) UPS, line-interactive UPS, online (double-conversion) UPS. The standby UPS system offers only the most basic features, providing surge protection and battery backup. Thus, its power supply quality is not good enough and the cost is much lower.
