Abstract :
Parallel redundant operation system using multiple power supply modules is suitable and acceptable for power supply system used in high reliability telecommunication system. Three prototype power supply modules are developed: single- phase 100 V 2 kVA module, single-phase 200 V 3 kVA module, and three-phase 200 V 2.5 kVA module. Any desired number of modules can be connected in parallel and are capable of redundant operation. Using these modules makes it possible to economically configure high-performance, high-reliability AC UPS systems capable of parallel redundant operation.
