摘要

This paper proposes a high-misalignment tolerant and auto-detuned wireless charging system (WCS), which has constant current/voltage (CC/CV) outputs and a lightweight receiver for the unmanned aerial vehicle (UAV). First, the system structure and operating principle are analyzed. The auto-detuned series–series (SS) compensation topology that improves the anti-misalignment capability of the system is realized by a magnetic flux-controlled inductor (MFCI). Then, the excellent y-axis anti-misalignment capability of the modified DD coupler (MDDC) is optimized to ensure the desired misalignment range. The transformer, which is the core component in the MFCI, is designed to provide a suitable control margin for CC/CV charging. Finally, simulation and experimental results verify the proposed method.
