Regional wireless power supply system

Abstract

The invention discloses a regional wireless power supply system working in a resonant mode, which comprises a metal conductor, an input terminal, an adjustable reactance terminal, an induction coil, apower receiving device of a user and a signal enhancing coil. One end of the metal conductor is connected with an input end, and the other end is connected with an adjustable reactance terminal. Themetal conductor, the input end and the adjustable reactance terminal together form a closed area. After the induction coil is connected with the power receiving device of the user, the induction coilis arranged in a plane surrounded by the closed area and a peripheral space thereof; When the tuned reactance terminal makes the metal conductor meet the resonance condition, the user power receivingdevice collects the electromagnetic wave energy passing through the area surrounded by the metal conductor through the induction coil and the signal enhancement coil and converts the electromagnetic wave energy into the required form to complete the wireless power supply. 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 resonance 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 development of...
