Design and Validation of a Multi-Port Converter for Renewable Energy Applications

Abstract

This paper presents the design, simulation, and experimental validation for a non-isolated multi-port converter (MPC) tailored for renewable energy applications such as microgrids and electric vehicles. The proposed converter architecture supports multiple power sources specially, a photovoltaic (PV) panel and a lithium-ion battery pack within a unified power interface. MATLAB Simulink was used for system-level analysis, and a hardware prototype was developed to confirm simulation accuracy. The control strategy dynamically adapts to three distinct operating modes based on source availability and load demand, thereby ensuring continuous and optimized energy delivery. Experimental results closely matched simulations, demonstrating the effectiveness of the proposed topology in achieving stable voltage regulation, efficient power sharing, and seamless mode transitions.
