Abstract
To meet the need that synergistic development of nano-satellite formation flying and wireless power transmission technologies, a space wireless power transmission system using a medium intensive sunlight has been introduced and designed. The system has sunlight converged with Fresnel lens, and changes the direction of converging sunlight beam with optical fiber. The heat attained from intensive sunlight is transformed into electricity by stirling engine in energy receive end. Efficiency of each link of the system has been obtained through design calculation of optical efficiency for energy resource platform elements and isothermal analysis for Stirling engine. Output power of 234.3 W was achieved on the order of 100 meter magnitudes, and the end-to-end efficiency of system was above 20 percent.
