Description

technical field [0001] The invention belongs to the technical field of inductive coupling electric energy and signal transmission, and in particular relates to a non-contact electric energy and two-way signal transmission method and system. Background technique [0002] Inductive coupling power transmission technology is a technology based on the principle of high-frequency electromagnetic field near-field coupling to realize short-distance non-contact transmission of power. At present, it has been more and more widely used in fields such as home appliances, oil drilling, implanted medical equipment, and electric vehicle charging. [0003] In many application scenarios, synchronous transmission of electric energy and communication signals is often required. The electric energy provides energy for the power receiving unit, and the signal communication is used to transmit control instructions, status information, sensor measurement values, etc. At present, a large number of a...
