چکیده: Abstract: In this research, the design and development of a robust controller for a medium-power DC–DC converter with a wide input voltage range is investigated. Given the growing demand for efficient power conversion systems in various industrial applications—particularly in the field of renewable energy and photovoltaic systems, which are subject to significant input voltage fluctuations—the primary objective of this study is to propose a novel approach that ensures output stability and reliability under varying input conditions. The proposed method is based on the two-switch forward converter topology, which offers notable advantages such as reduced voltage stress and improved efficiency. Furthermore, to enhance flexibility and system performance, artificial intelligence techniques are integrated into the controller design. This approach improves the system’s dynamic response while simultaneously guaranteeing optimal performance across a wide range of power and voltage levels. Simulation results and performance analysis demonstrate that the studied converter, when equipped with the proposed intelligent controller, is capable of maintaining output voltage stability and achieving higher efficiency, thereby addressing the diverse requirements of modern industries and electric vehicle charging infrastructures. The main contribution of this research lies in the integration of artificial intelligence techniques into converter control and the utilization of the two-switch forward topology for medium-power, wide-input applications, which together contribute to improved power quality and enhanced stability of power networks.
