Abstract

This article presents a novel four-port DC–DC converter designed to integrate photovoltaics, fuel cells, and supercapacitors with one DC charging single-output port with a reduced component count. The proposed converter ensures an efficient power management strategy to manage the load power demand and optimize the power flow from the sources. The power management controller helps enhance the performance of the system by dynamically prioritizing the sources based on their availability and the demand of the load. A comprehensive reliability analysis is conducted to measure the converter’s robustness under varying load conditions, proving its suitability for real-world applications. The proposed topology’s performance was validated in three different scenarios for 1 kW using a simulation tool, and experiments in the laboratory were conducted. The failure rate and efficiency of the system are analyzed, and the converter promises a 96.5% efficiency for 1 kW and a failure rate of 4.6216 × 10 6 failures per hour. The simulation and experimental results validate the converter’s performance, highlighting its superior efficiency, reliability, and scalability.
