A wireless energy information synchronous transmission system

Abstract

The invention provides a wireless energy and information synchronous transmission system, which comprises a signal modulator (1), a first coupling transformer (2), an alternating current source (3), afirst multi-resonant unit (4), a main coupling coil (5), a second multi-resonant unit (6), a second coupling transformer (7), a load (8) and a signal demodulator (9). The multi-resonant units are constructed, and the multi-resonant units at least include two resonant frequencies, a signal frequency is introduced on the basis that the good energy transmission performance is guaranteed, and the tworesonant frequencies and the signal frequency cannot interfere with each other during synchronous transmission. According to the system, both the energy and the information can obtain the optimal transmission characteristic. Meanwhile, the invention further provides a signal coupling transformer capable of adjusting a coupling coefficient, and a purpose of adjusting the signal receiving voltage and the signal-to-noise ratio of a communication system can be achieved by adjusting a rotating angle of the coupling transformer.
