UPS Topologies - Project Performance Comparisons
Four common UPS system topologies are compared for dependability and whole-of-life performance. Based on recent projects designed and constructed, this is a case study approach to the puzzle of “which UPS topology best suits my project?”. Dependability comparison combines availability, reliability, maintainability, and system safety. Whole-of-life considers the overall project build cost (equipment, switchgear, supporting plant, and required space), the maintenance and operating costs, the repair and procurement times, the quality and Tier performance, through the range of energy storage options normally used for each topology. We also briefly consider some alternate topologies not in common use.
