What is an uninterruptible power supply (UPS)?
An Uninterruptible Power Supply (UPS) is a device designed to provide backup power when the primary power source fails or when voltage levels drop below acceptable limits. UPS systems are commonly used in computers, server farms, and data centers to ensure uninterrupted operation and protect digital data from power-related disruptions.
What is backup uninterruptible power supply?
15.1.3.1. Backup uninterruptible power supply Fig. 15.2 shows the structure of the backup UPS. The backup UPS directly supplies power to the load from the grid when the utility power is normal. At this time, the inverter of the UPS does not work, and the grid charges the battery if the battery is not fully charged.
What are the different types of uninterruptible power supplies?
There are two main categories of uninterruptible power supplies (UPSs) 1, static and rotary. As the name implies, static UPSs do not have any moving parts in their con-verters. Whereas, rotary UPS use mechanical parts that rotate, such as motor/gen-erators, to function. This paper focuses only on static UPSs.
What is a rotary uninterruptible power system?
A UPS is normally referred to as an uninterruptible power supply, but it’s also known as uninterruptible power system. Note that rotary UPS are covered in IEC 88528-11:2004 Reciprocating internal combustion engine driven alternating current generating sets - Part 11: Rotary uninterruptible power systems - Perfor-mance requirements and test methods.
What are the different types of UPS system?
UPS system can be classified on the basis of the topologies and circuit configuration. The UPS system may be transformer-based, transformer-less, or high frequency transformer based. These UPS system are developed in the variety of configurations in order to fulfil the exact requirement of the application.
What is unified control scheme for uninterruptible power supply system?
Conceptual diagram of unified control scheme for uninterruptible power supply system. Because of the three-phase four-wire configuration, the control for each phase in both the PWM rectifier and inverter can be decoupled. Therefore, a single-phase independent control approach can be adopted.
