Abstract

The invention relates to a wireless power transmission technology, in particular to a working condition adaptive multi-channel interconnection wireless power supply system and method. The wireless power supply system comprises a DC power supply, a plurality of transmitting units, a plurality of receiving units, a power supply state detection module, a control module, a load state detection module, a rectification and voltage stabilization module and a load, wherein the DC power supply is respectively connected with the plurality of transmitting units and the power supply state detection module, the control module is respectively connected with the power supply state detection module and the load state detection module, and the load is respectively connected with the load state detection module, the plurality of receiving units and the rectification and voltage stabilization module. According to the working condition adaptive multi-channel interconnection wireless power supply system, a magnetic coupling resonant wireless power transmission technology is adopted, a transmitting coil is optimally designed, and the influence of the wireless charging system on the outside is reduced by reducing a vertical coupling magnetic field of the coil. The wireless electric energy transmission power is changed by changing the number of the wireless charging coupling mechanisms, so that the wireless charging system can meet the charging requirements of loads with different power levels.

Description

technical field [0001] The invention belongs to the technical field of wireless power transmission, and in particular relates to a working condition adaptable multi-channel interconnected wireless power supply system and method. Background technique [0002] Wireless power transmission technology is currently widely used. According to the more common power transmission mechanism, it can be divided into three forms: electromagnetic induction, radiation and electromagnetic resonance. [0003] Electromagnetic induction wireless power transmission technology is based on the induction principle of the separation transformer to realize the non-contact transmission of energy. The high-frequency current is passed into the primary side coil, and the inductive coupling of the magnetic field is used to transmit energy from the primary side and couple to the secondary side to generate an induced current. . It has the advantages of higher transmission power and efficiency, but its trans...
