Implementation of Single-Inductor DC/DC Converter with Fully Reconfigurable Structure for Renewable Energy Applications

A novel non-isolated three-port converter (NITPC) is used in this project. The purpose of this topology is to integrate a renewable energy and DC bus, instead of the widely reported consuming load, with a photovoltaic (PV)-battery system. Conventional methods require either a separate dc-dc converter to process the reversible power flow or employing an isolated three-port converter (TPC) which allows bi-directional power flow between any two ports. However, these methods require many switches which increases the converter size and control complexity. This project presents a compact but fully functional design by combining and integrating basic converters to form a simplified single inductor converter structure while keeping minimum number of switches. The resultant converter is fully reconfigurable that all possible power flow combinations among the sources and load are achieved through different switching patterns. In existing system, the single source (PV) will be used. So, the unidirectional power flow only possible. But In our proposed system Hybrid energy will be used. So, if any case in the system will be stable
