Abstract

The invention discloses a space millimeter wave wireless energy transmission system. The space millimeter wave wireless energy transmission system comprises a klystron power source; a continuous transmitting millimeter wave klystron connected with the klystron power source, a millimeter wave transmitting antenna of which an input end is connected with the millimeter wave klystron, a receiving antenna array which is arranged in the free space, is arranged corresponding to the millimeter wave transmitting antenna and comprises at least one receiving antenna, a rectifying circuit of which an input end is connected with an output end of the receiving antenna array, a DC power synthesizing circuit of which an input end is connected with an output end of the rectifying circuit, a three-port converter of which an input end is connected with an output end of the DC power synthesizing circuit, a load of which an input end is connected with an output end of the three-port converter, and a battery connected with the three-port converter. The system is advantaged in that wireless energy transmission is carried out through utilizing a millimeter wave band, high aspect ratio energy transfer is realized, and a problem of lacking of practicality caused by the excessive volume and weight of a conventional microwave energy transmission system needing equipped with transmitting / receiving antennasis overcome.

Description

technical field [0001] The invention relates to the technical field of microwave wireless energy transmission systems in energy sources, in particular to a space millimeter wave wireless energy transmission system. Background technique [0002] As early as the 1960s, people put forward the concept of solar space power station based on microwave energy transmission technology. In the field of solar space power stations, a lot of research has been done abroad. Compared with traditional energy transmission methods, microwave energy transmission technology has its unique advantages, such as no transmission medium, fast speed, low loss, and easy re-layout, etc. However, due to the low frequency of the microwave energy transmission system in the traditional band, the transmitting / receiving antenna array is huge and weighs several tons, which is not very practical. Contents of the invention [0003] The purpose of the present invention is to provide a space millimeter wave wirel...
