A wireless energy information synchronous transmission system

Abstract

The invention proposes a wireless energy information synchronous transmission system, including a signal modulator (1), a first coupling transformer (2), an AC source (3), a first multi-resonance unit (4), and a main coupling coil (5) , the second multi-resonance unit (6), the second coupling transformer (7), the load (8) and the signal demodulator (9). The invention constructs a multi-resonant unit, which contains at least two resonant frequencies. On the basis of ensuring good energy transmission performance, a signal frequency is introduced, so that the two can achieve mutual non-interference during synchronous transmission. The invention enables both energy and information to obtain optimal transmission characteristics. At the same time, the invention also provides a signal coupling transformer that can adjust the coupling coefficient. By adjusting the rotation angle of the coupling transformer, the purpose of adjusting the signal receiving voltage and signal-to-noise ratio of the communication system can be achieved.
