An uninterruptible power supply or uninterruptible power source (UPS) is an electrical apparatus that provides emergency power to a load when the input power source or mains power fails. A UPS differs from an auxiliary or emergency power system or standby generator in that it will provide near-instantaneous protection from input power interruptions, by supplying energy stored in batteries, super capacitors, or flywheels.
TYPES OF UPS
1. Industrial UPS
For use in industrial/manufacturing situations, such as plant facilities and factories.
2. Medical UPS
Used in hospitals and medical centers, Medical UPS systems are incredibly important, as they support life-support systems and other critical equipment.
3. Computer and Communication System
Found in server farms and web hosting sites, along with phone companies, computer/communication UPS is probably the most commonly known to the average person, but they range from those made for a home-office to those that
4. Standby UPS
Standby UPS, also known as off-line or line-preferred UPS, typically consists of an AC/DC and DC/AC inverter, a battery, a static switch, a low pass filter to reduce switching frequency from the output voltage, and a surge suppressor. The standby system operates with the switch setting the AC input as a primary power source, and alternating to the battery and inverter as backup sources in case of primary power failure. The inverter normally remains on standby, only activating when the power fails and the transfer switch automatically switches the electrical load to the backup units. This type of UPS system provides a high degree of efficiency, small size, and relatively low costs, making it a common option for personal computing.
5. Double Conversion
Double conversion UPS systems are commonly used for higher voltage applications and they feature a configuration similar to those of standby units, but with a primary power path focused on the inverter rather than the AC main. This type of UPS system takes virtually no time to transfer between modes because input AC power failure does not trigger the transfer switch. Instead, the input AC charges the backup battery, which in turn powers the output inverter. This configuration results in highly efficient electrical power performance, but may cause long-term wear on components and can occasionally interfere with power wiring or standby generators.
CHARACTERISTICS OF UPS
1. Regulated output voltage with low harmonic distortion unaffected by input voltage or load changes
2. An input current with reduced harmonic distortion
3. A low degree of electromagnetic interference and acoustic noise
4. Minimal transition times between normal and backup operations
5. High levels of reliability and efficiency
6. Relatively low cost, weight, and size requirements
Although most individual power supply systems cannot provide all of these features simultaneously, it is usually possible to find a UPS with the characteristics suited to an application’s needs. The Department of Energy’s Office of Scientific and Technical Information provides more information on harmonics measurements.
