Comparing uninterruptible power supply topologies
By Uninterruptible PowerSupplies Limited
Today, uninterruptible power supply (UPS) systems are typically employed to support data centers, communications hubs and other applications using sensitive ICT equipment. These installations’ continuous availability is usually critical to their owners’ survival, so a clean, uninterrupted power supply becomes a business-critical requirement.
This article compares on line and off line UPS topologies, together with a third variant – line interactive topology. As rising energy costs sustain the demand for better energy efficiency, this article also reviews Eco mode UPS operation and its contribution to improved PUE. For more, click here.
