Description

technical field [0001] The invention belongs to the technical field of magnetic coupling resonance wireless power transmission, relates to a variable topology magnetic coupling resonance wireless power transmission system, and in particular to a method for increasing transmission power by changing the topological structure of a transmitter module and a receiver module. Background technique [0002] Since Nikola Tesla proposed the theory of wireless power transfer a century ago, wireless power transfer has been a hot research topic. Experts at home and abroad have been conducting research on wireless power transmission for many years, but the progress of scientific research has been slow until June 2007. Marin Soljacic, a professor of physics at the Massachusetts Institute of Technology (MIT), and his team members proposed a magnetic coupling based on strong magnetic coupling. A new scheme of resonance. In the experiment, two coils with a diameter of 60cm and copper wires wer...
