  • Abstract
    An n+1 redundant system using modular hybrid DC/DC converters connected in parallel where the normally associated isolation diodes are omitted is described. Reliability and efficiency analysis of the systems was performed, based on a comparison between the system described and a system based on a conventional (uninterruptible power system) UPS with added redundant functions. It is concluded that the proposed approach will lead to an improvement in overall efficiency and result in compact, cost-effective systems
