摘　　要：In order to address the future power generation needs for scientific exploration of the lunar permanently shadowed regions,this paper proposes a laser wireless power transfer(LWPT)system from a power source at the illuminated rim of the crater to a photovoltaic laser receiver on a rover exploring inside the permanently shadowed region.To fill a gap between the conceptual design and an operational system,the required conditions were analyzed regarding the effects of beam alignment and shaping,wavelength-dependent conversion efficiency on the system level efficiency,and a ground-based prototype system was established.Electric–electric efficiency of 11.55%was measured at a ground transmission distance of 10 m.The study is complemented by discussing optimization analysis for subsequent research,can be more effective and employed in the future.
