Abstract

The invention relates to a wireless magnetic coupling link based on artificial intelligence and a method for adjusting output voltage of a receiving end at a transmitting end. The link comprises the transmitting end and a transmitting coil for outputting energy, a receiving coil for receiving energy, the receiving end and a load connected with the receiving end. The TX local output voltage regulation module comprises an artificial intelligence module, an ADC module and a low-pass filter module, the artificial intelligence module is of a full-connection neural network structure, and the transmitting end voltage VL is input into the artificial intelligence module through the sampling amplitude of the low-pass filter module and the ADC module; and the artificial intelligence module is used for extracting the condition that the output voltage VO of the receiving end deviates from a set value from the voltage VL of the transmitting end and the constant voltage cannot be kept, and adjusting the output power of the transmitting end in time through the input voltage VIN of the transmitting end. The method has the beneficial effect that the uplink data transmission bandwidth is not occupied or the light load efficiency is not reduced.
