Multi-Port Non-Isolated DC-DC Converters and Their Control Techniques for the Applications of Renewable Energy

Abstract

In recent times, the increasing demand for energy consumption on a global scale and the prevalent use of power electronics DC-DC converters in various applications, such as hybrid energy systems, hybrid vehicles, aerospace, satellites, and portable electronic devices. To increase the converters’ dependability, effectiveness, adaptability, and cost-effectiveness, they have undergone substantial research and development. Diverse input levels can be merged for diverse output levels using new converter topologies, which increase their possibilities from single input-single output setups to multi-input-multiple configurations. The goal of ongoing research is to lower costs and component counts while raising efficiency and dependability. This review paper focuses on the analysis of non-isolated converters, especially for SI-MIMO topologies produced from different converter types. The research work, also includes control techniques and methods like proportional integral derivative, sliding mode control, model predictive control, state-space modelling, fuzzy logic control, and maximum power point tracking, which are all integrated with non-isolated DC-DC converters while considering things like settling concerns, response time, and complexity.
