Abstract

The invention discloses a two-dimensional wireless power supply method based on a coupling relay. A plurality of rectangular energy coupling units form a two-dimensional wireless energy relay plane, and an energy transmitting coil and an energy receiving coil are arranged on the two-dimensional wireless energy relay plane. In the energy transmitting coil, the output end of the high-frequency signal source is connected to the transmitting antenna through an amplifier, and the high-frequency energy generated by the high-frequency signal source is amplified by the amplifier and coupled to the nearest rectangular energy coupling unit by the transmitting antenna. In the rectangular energy coupling unit, the rectangular coil induces a current to generate its own electromagnetic field and transmits the high-frequency wireless energy to the adjacent rectangular energy coupling unit. In the energy receiving coil, the receiving antenna obtains high-frequency energy from the nearest rectangular energy coupling unit, and then rectifies it to obtain DC current which is filtered and transmitted to the load. The invention is suitable for the wireless high-frequency energy receiving device to movefreely on the plane, has high system flexibility and avoids excess space energy dissipation.

Description

technical field [0001] The invention relates to a two-dimensional wireless energy supply method, in particular to a two-dimensional wireless energy supply method based on coupling relays. Background technique [0002] Typical applications for wireless power include cell phone charging, electric vehicles, robotics, and implanted medical devices, among others. Compared with the traditional wired power supply method, the wireless power supply method avoids the cable connection problem of the power consumption terminal, so that a stable and continuous energy supply can be obtained even in places where it is inconvenient to use cables. In addition, the rapidly increasing wireless energy supply method in motion in recent years can continuously supply power to the power consumption target during its movement, which can greatly reduce the battery capacity of long-term, high-power power consumption equipment. However, most of the existing wireless energy supply methods in motion use...
