Title: Wireless power transmission system
Inventor: KONO RYUJI
IPC: H01Q25/00
Filed: 2019-03-25
Abstract: To abate, during wireless power transmission using microwaves, the deterioration of the power transmission efficiency of long-distance electric power transmission caused by a decrease of a power density proportional to the square of a power supply distance.SOLUTION: A wireless power transmission system according to the present invention uses multihop relay for transmitting power through relaying by a relay device which is added between a power transmitter and a power receiver. Since power is transmitted by using multihop relay, the distances between nodes of the power transmitter, the power receiver, and the relay device in a transmission system become short. Accordingly, the influence of attenuation according to the transmission distance is reduced. The long-distance power supply efficiency is increased by power transmission using multihop relay via the relay device, compared to a case where direct power transmission is performed between the power transmitter and the power receiver. Also, an interference to a human body or any other wireless device is avoided.SELECTED DRAWING: Figure 1
