| Summary: | Introduction. In view of growing environmental concerns, innovative solutions to ensure electrical energy supply to various devices and systems are required. As a result, renewable energy sources, including those based on solar energy, are attracting much attention. In this context, the development of a Wi-Fi router powered by modern photovoltaic converters seems to be a relevant research task.Aim. Development of a Wi-Fi router powered by modern photovoltaic converters.Materials and methods. The proposed system was developed on the basis of a Wi-Fi router YF360-H and a photovoltaic cell HVL-105/O.Results. Calculations of the developed photovoltaic system were performed; volt-ampere and watt-ampere characteristics of the solar panel were investigated. The solar panel power supply circuit was developed, with the conversion efficiency in the working area achieving 90 %. The capacity of the external battery ensuring the system's autonomous operation for 7 days was determined. A modeling experiment in the MATLAB environment demonstrated the high efficiency of the developed system.Conclusion. According to the conducted calculations, a HVL-105/O photovoltaic cell can be used to power a Wi-Fi router YF360-H under the weather conditions considered most unfavorable for solar cells. |
