Abstract

This paper describes how the power electronics software PSIM was used to design and simulate a bidirectional full-bridge DC–DC converter. The goal is integrating hybrid storage system into a photovoltaic microgrid. The objective is to manage power flow between sources and storage devices in order to smooth transients, reduce current stress on the battery, and maintain appropriate voltage levels on the DC bus. Due to the limitations of the evaluation version of the circuit simulation program, equivalent elements were employed to reproduce the quasi-stationary behavior of the photovoltaic array, the battery bank, and the super capacitor module. Seven representative operating scenarios were analyzed (charging/discharging in both directions, super capacitor support, and power transfer from/to generation), evaluating key voltages and currents. The results demonstrate effective bidirectionality and high-frequency power decoupling capability provided by the supercapacitor, with positive implications for battery lifetime. In addition, a prototype-level cost estimation is included, and limitations and future work focused on dynamic control and experimental validation are discussed.
