Area wireless power supply system

Abstract

The invention discloses a regional wireless power supply system working in a traveling wave mode, which comprises a transmission line, an input terminal, a matching load terminal, a signal enhancementcoil, an induction coil and a user power receiving device. One end of the transmission line is connected with an input end, and the other end is connected with a matching load end to form an annularclosed area as a whole. After the induction coil is connected with the power receiving device of the user, the induction coil is arranged in a plane surrounded by the closed area and a peripheral area; When the transmission line satisfies the traveling wave transmission condition, the user power receiving device collects the electromagnetic traveling wave energy passing through the transmission line surrounding area through the induction coil and the signal enhancement coil and converts the electromagnetic traveling wave energy into the required form, so that the wireless power supply can be completed. The system of the invention is simple in principle, convenient in implementation, high in overall utilization efficiency of energy and low in cost, and has a wide application prospect.

Description

technical field [0001] The invention relates to a wireless power supply system, in particular to an area wireless power supply system working in a traveling wave mode. Background technique [0002] As a basic structure of modern society, the power supply system undertakes the transmission of electric power and plays a very important role. The conduction medium of most power supply systems is a metal good conductor, the physical structure is a cable, and the working form is DC or very low frequency AC. This is because the metal wire system can provide high-capacity, long-distance and low-loss power transmission. [0003] Wireless power supply system, as the name suggests, is to supply power to power terminals in a non-cable or non-contact way; its concept was first proposed by Nikola Tesla, and its history can be traced back to a hundred years ago. Due to technical reasons, After that, it has not been further studied and widely promoted. In recent years, with the developme...
