Problems solved by technology

In order to obtain higher energy conversion efficiency, the magnetically coupled resonant device uses a single-frequency sinusoidal signal as the energy transmission carrier, and the sinusoidal signal has a theoretical bandwidth of zero and cannot carry information.

Therefore, the traditional magnetically coupled resonant energy and information synchronous wireless transmission device adopts energy-concentrated single-frequency signals to ensure transmission efficiency in energy transmission, and uses narrow-band signals in signal transmission, which can only transmit a small amount of information.
