How does an Uninterruptible Power Supply (UPS) work?

UPS is also known as battery backup. UPS provides backup power to your equipment when your regular power supply break or voltage drops. A UPS proves you’re the facility to properly shut down your system after proper saving of work, so it prevents data loss on sudden power supply cut.

Types of UPS Topologies-

  • Standby
  • Line-interactive
  • Double-conversion(online)

  1. Standby is basic topology, in this topology UPS provides backup when a common problem such as voltage surge or blackout raises.

  1. In-Line Interactive UPS topology correct minor fluctuation in power supply during under-voltage and over-voltage.Line-interactive UPS topology is generally used for consumer electronics such as PCs, network-system, and servers.

  1. In Double-conversion (online topology) UPS converts incoming AC to DC and then back to AC. This type of UPS has zero transfer time and so does need to switch on DC power. This type of UPS uses for protecting high-end and critical IT equipment and servers.
