太阳能无人机电源系统综述

In view of the lack of systematic research on solar unmanned aerial vehicles (UAV) in China，the development status of solar unmanned aerial vehicles was discussed from the aspects of solar panels，energy storage systems，power converters，etc.，according to the main functional units of the power system. The representative research results at home and abroad were summarized. It was found that the performance of the solar UAV power system was one of the key factors affecting its continuous operation. The main research issues included: improving the conversion efficiency and physical characteristics of photovoltaic cells，improving the energy density and stability of energy storage units，and equipping the corresponding energy management system. Finally，the development direction of solar UAV power system was summarized: from the research and development of high-performance solar cell materials， to the research on the diversity of energy storage systems and the improvement of environmental adaptability，and then to the design of high-power and high-efficiency power converters and the intellectualization of energy management， finally to improvement of the energy utilization rate and realization of the miniaturized and lightweight system.
