Embodiment Construction

[0036] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will be described in detail in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the invention.

[0037] The basic structure of a typical ICPT system is as follows: figure 1 As shown, the rectification and filtering link rectifies the power-frequency alternating current into direct current, and then undergoes high-frequency inverter to become high-frequency alternating current, which is injected into the transmitting coil on the primary side. The transmitting coil generates a high-frequency alternating magnetic field in the nearby space, and the receiving coil on the secondary side The induced voltage is generated, and then rectified and filtered to provide a DC output for...

Abstract

The invention discloses a full duplex communication ICPT system based on a shared channel. The system comprises a power supply circuit, a primary side electric energy resonance circuit, a secondary side electric energy resonance circuit and a load circuit. A part of a winding of an electric energy transmitting coil in the primary side electric energy resonance circuit is used as a primary side signal transmission coil, and primary side signal channel circuits are connected in parallel to two ends of the main circuit, thereby forming the primary side signal resonance circuit. A part of a winding of an electric energy receiving coil in the secondary side electric energy resonance circuit is used as a secondary side signal transmission coil, and secondary signal channel circuits are connectedin parallel to the two ends of the circuit board, thereby forming the secondary side signal resonance circuit. A signal resonance network formed by the primary side signal resonance circuit and the secondary side signal resonance circuit is provided with at least two resonance points. According to the invention, the system structure can achieve the electric energy transmission and signal transmission in mutually independent resonant networks, and a part of the electric energy transmission networks has a wave blocking function, so that the signal transmission cannot influence the transmissionof electric energy, and the quality of the signal transmission and the electric energy transmission is ensured.

Description

technical field [0001] The present invention relates to the technical field of wireless power transmission, and more specifically, relates to a shared channel-based full-duplex communication ICPT system. Background technique [0002] Wireless Power Transfer (WPT) technology is to transmit power wirelessly, which is safer and more flexible than the traditional cable power-taking method. At present, WPT technology has attracted more and more attention, and its related applications have become more and more abundant. The research on its application is mainly concentrated in the fields of implantable medical equipment, electric vehicles, consumer electronics and other fields. Among them, inductively coupled power transfer (ICPT) technology is the most widely used. It uses the principle of electromagnetic resonance to realize wireless transmission of power from the primary side to the secondary side. It has better performance in high-power and appropriate spacing application scen...
