Développement of MOSFET -Based Reversible Static Converter for photovoltaic Energy Systems

Abstract

Thisthesis presentsthe design and implementation of a reversible electric converter utilizing MOSFET technology. The primary objective is to develop a bidirectional power conversion system capable of operating efficiently in both rectification and inversion modes. Such converters are essential in modern power electronics, particularly in renewable energy systems, electric vehicles, and energy storage applications, where power flow needs to be controlled in both directions. The work begins with a detailed analysis of the principles of reversible converters and the role of MOSFETs as fast-switching, high-efficiency components. The design process includes selecting appropriate topology, component sizing, and developing a control strategy to ensure stable and reliable operation. Simulation models are developed using specialized software to validate the theoretical approach, followed by hardware implementation and experimental testing. The results demonstrate that the proposed MOSFET-based converter achieves high efficiency, fast switching performance, and robust bidirectional control. This study highlights the potential of MOSFETs in advancing compact, reliable, and energy-efficient power conversion systems.
