Aimed at the problem of lateral offset in the magnetic coupling device of a wireless charging system for rotorcraft unmanned aerial vehicles (UAVs), a self-alignment method of coils is proposed by collecting the output voltage while moving the transmitting coil and adjusting its position according to the value of the collected output voltage. First, a mutual-induction model is established to analyze the electrical and magnetic characteristics of the wireless charging system, thereby deriving the expression of the relationship between the output voltage and the lateral distance between the transmitting and receiving coils. Then, the size of a magnetic coupler is designed based on the size of the alignment region, and the alignment regionis divided. Additionally, a specific alignment process is outlined. Finally, an experimental platform was established to conduct self-alignment experiments on the transmitting and receiving coils. Based on the experimental results, it is evident that the proposed method can effectively achieve self-alignment of coils with an alignment accuracy of less than 1.5 cm, meeting the requirements for efficient wireless charging of UAVs.
