Abstract

Due to increasingly demand of power in each area, power cut is regular phenomena. Even an interruption for few cycles of power supply, results in losses of data storage, mal functioning of various sensitive equipments. Various methods have been reported in literatures to provide continuous power supply such as uninterrupted power supply, battery system and others non conventional source of energy (Solar and Wind system). In this paper a model is developed to maintain regular power to consumers even interruption in power supply occurs for few cycles. Mathematical model is developed under different modes of operation such as normal, back-up and charging. Three winding high frequency transformer is designed to interface utility and battery back-up system with load. A 50 Watts integrated fly back converter for DC uninterruptible power supply is designed and tested.
