The invention relates to the technical field of wireless charging, and particularly discloses an unmanned aerial vehicle convenient wireless charging system based on high-voltage line energy taking, the unmanned aerial vehicle convenient wireless charging system comprises an overhead high-voltage line and a wireless receiving end installed on an unmanned aerial vehicle, the wireless receiving end comprises a secondary side coil L1 and a secondary side coil L2, and the wireless receiving end further comprises a secondary side resonance circuit, a power controller and an output circuit. The secondary side resonant circuit is formed by connecting a capacitor beside each of two diodes in parallel on the basis of a common anode (diode) electrode connection type current doubling rectifying circuit topology, and the capacitor is 0 lt; tlt; 1/2fr and 1/2frlt; tlt; and within the 1/fr time, the polar capacitors C2 and C3 alternately compensate and circulate to form a high-power density capacitor, so that the problem that the size of the AC resonant capacitor is too large is ingeniously solved. According to the designed current-doubling rectification power electronic converter, under the condition that the volt-ampere characteristic of the coupling mechanism is not changed, the equivalent current in the coupling mechanism and the resonant network of the ultralow-frequency wireless power transmission system is reduced, so that the structural weight is further reduced, and the system power density is improved.
