Analysis of Multi Input Transformer Coupled Bidirectional DC-AC Converter for Hybrid System

Abstract

A highly efficient multi input transformer coupled bidirectional DC - DC converter regulates the flow of electricity in a hybrid energy system, allowing it to meet demand, regulate power flows from multiple sources, inject surplus energy to the grid, and charge the battery from the grid as needed. Grid-connected hybrid systems and other ripple voltage filters require more stages of power conversion, components, and incur losses than the suggested converter type. A PI and FOPID controller is also used in grid-connected systems to improve voltage regulation. The results are simulated using MATLAB/SIMULINK.
