第一期比尔·布朗 SSP 技术讲座涵盖了最先进的 (SOA) 无线电力传输 (WPT) 技术，包括用于传输 CW 电力的微波和激光系统，与最终开发的空间太阳能 (SSP) 系统相关。介绍了当前和过去在地面和空中和空间应用的能量转换装置、系统和建模信息方面的技术成就，其中这些数据是作者已知的。演示的目的是讨论和展示数据，鼓励记录和打破当前记录，从而推进 SSP 的 WPT 中的 SOA。例如，对于 DC 到 RF 和激光转换器，效率为 83% 的 2.45 GHz 炊具管磁控管； CPII 和俄罗斯人已开发出 800 W CW 输出。 LLNL 已在 808 nm 波长下开发出超过 50% 的电光转换效率 1.5 kW/cm(2) CW、水冷、多光束、固态激光二极管阵列。德国人开发出了效率 36%、kW 级、单相干光束、横向泵浦半导体激光器。 1975 年 Raytheon-JPL 实验期间实现了 54% 的转换效率，在 1.7 米范围内恢复了 495.6 W，频率为 2.4469 GHz端到端直流输入到直流输出功率的记录整体 WPT 链路转换效率在 1975 年雷神-JPL 实验期间实现了 54%，在 1.7 米范围内恢复了 495.6 W，频率为 2.4469 GHz 1975 年 Bill Brown 和作者在加利福尼亚州戈德斯通进行 JPL-Raytheon 实验期间，有效恢复电功率输出（与结构中的热感应功率相比）的记录是 1.55 km 范围内 34 kW 直流输出，使用 2.388 GHz 微波。GaAs 二极管整流天线阵列的平均收集转换效率为 82.5%。单个整流天线。 Bill Brown 开发的元件显示出 91.4% 的效率。对于 1.7 W 和 826 nm 波长的 AlGaAs，激光到光伏直流输出功率转换效率的可比记录为 59%。 (C) 2003 年，爱思唯尔科学有限公司出版。
This first Bill Brown SSP Technology Lecture covers the state-of-the-art (SOA) in wireless power transmission (WPT) technology including microwave and laser systems for the transfer of CW electric power, as related to eventually developing Space Solar Power (SSP) systems. Current and past technology accomplishments in ground based and air and space applied energy conversion devices, systems and modeling information is presented, where such data are known to the author. The purpose of the presentation is to discuss and present data to encourage documenting and breaking the current records, so as to advance the SOA in WPT for SSP.For example, regarding DC to RF and laser converters, 83% efficient 2.45 GHz cooker-tube magnetrons; with 800 W CW output have been developed by CPII and the Russians. Over 50% wall-plug efficient 1.5 kW/cm(2) CW, water-cooled, multibeam, solid state laser diode bararrays have been developed by LLNL at 808 nm wavelength. The Germans have developed a 36% efficient, kW level, single coherent beam, lateral pumped semiconductor laser. conversion efficiency is 54% achieved during the Raytheon-JPL experiments in 1975 for 495.6 W recovered at 1.7 -m range, at 2.4469 GHzThe record for end-to-end DC input to DC output power overall WPT link conversion efficiency is 54% achieved during the Raytheon-JPL experiments in 1975 for 495.6 W recovered at 1.7-m range, at 2.4469 GHz The record for usefully recovered electric power output (as contrasted with thermally induced power in structures) is 34 kW DC output at a range of 1.55 km, using 2.388 GHz microwaves, during the JPL-Raytheon experiments by Bill Brown and the author at Goldstone, CA in 1975. The GaAs-diode rectenna array had an average collection-conversion efficiency of 82.5%. A single rectenna. element developed by Bill Brown demonstrated 91.4% efficiency. The comparable record for laser light to DC output power conversion efficiency of photovoltaics is 59%, for AlGaAs at 1.7 W and 826-nm wavelength. (C) 2003 Published by Elsevier Science Ltd.
