Transformer less Intelligent UPS System for Smart Grid to Meet the Reliable Energy by Designing H-Bridge Converter

Ravi Angadi | S. Zabiullah ^[2]

Abstract: In the present scenario all sector needs continuous power supply to meet our day to todays demand. To achieve these parameters like voltage, current and frequency of the power system should be at rated values, because of remote generation, transmission and distribution we are failing to receive the reliable power. In view of this we are proposing transformerless intelligent uninterruptible power supplies (UPS) for smart grid to meet the reliable energy which operates in multi-functional modular, intelligent UPS system for smart grid consists of four identical H-bridge converters. This concept will include the SPWM techniques to achieve the commanding of intelligent UPS system, also not only can realize all the basic functions of the traditional on-line UPS system, but also can gives pictorial path for the cyclic use of the electrical power between the power grid and storage battery. In the proposed system also we can easily interface the renewable energy sources in order to achieve the sustainable energy. Moreover, due to the modular design, it can easily operate in any power converters mode for any applications. The configuration and working principle of the proposed IUPS system are analyzed, and controlling is achieved by designing and modeling of intelligent UPS system and results are verified with the help of MAT LAB/Simulink.
