摘　　要：小型电动无人机在情报获取、战场监视等方面发挥着重要作用,但续航时间短的问题严重限制其效能的发挥。为解决该问题,采用激光无线能量传输技术为飞行中的无人机进行充电,大幅提高其续航时间,增强作战效能。光伏接收器作为能量转换器件,是系统设计需要考虑的核心器件之一。以电动无人机激光供能系统结构原理为基础,针对小型电动无人机的特点,提出在设计光伏接收器时所应满足的具体性能要求,并对影响光伏接收器设计的五个主要因素:系统工作模式,光伏电池,接收器结构布局,散热系统和角度衰减系数进行分析,为光伏接收器的设计提供基础研究。Small unmanned aerial vehicle（UAV） powered by electricity plays an important role in modem war, inclu- ding intelligence acquisition, battlefield reconnaissance and so on. But short operation time severely constricts its ap- plication. To solve the problem,laser wireless power transmission is adopted to refuel the UAV in flight. Photovohaic receiver converting optical energy into electricity is one of the key components of the system. Based on the principle of laser powered UAV and the feature of small UAV powered by electricity, the performance requirements of photovoltaic receiver are proposed. Correspondingly, five main factors influencing design of photovohaic receiver are analyzed, such as operation mode, photovoltaic cell, structure and layout of receiver, cooling system and angle attenuation coeffi- cient. It provides a reference for design of photovohaic receiver.
