基于微波无线能量传输的临近空间飞行器电力供给

摘要

Microwave power transmission ( MPT) which has the characteristics of high efficiency and high atmosphere transparence ,is the research emphasize of long distance WPT .International studies on WPT have lasted over sixty years . Space solar power is considered as the long term application and near-space vehicle is considered as the near term and mid-dle term application .The background of WPT and the some important experiments are introduced firstly .The composition and the key technologies of a typical MPT system are analyzed .The development roadmap of microwave power transmission tech-nologies used for near -space vehicles is proposed and the technical specifications of three stage MPT experiment systems are presented .%微波无线能量传输具有较高的效率，大气穿透性好，是远距离无线输电研究的重点。国际上以空间太阳能电站为远期应用目标、以航空器平台远距离无线供电为近中期目标，对于微波无线能量传输技术开展了几十年的研究。文章在国外发展现状基础上，初步分析了微波无线能量传输系统组成及核心技术，提出临近空间飞行器电力供给用微波无线能量传输技术的发展路线图，并给出临近空间飞行器电力供给微波无线能量传输系统的分阶段发展技术指标建议。
