The invention discloses an unmanned aerial vehicle wireless charging system and method based on an LCC-P topology compensation network. The system comprises a transmitting end and a receiving end, wherein the transmitting end comprises a direct-current power supply, a full-bridge high-frequency inverter, a primary side LCC topology compensation network and a primary side coil which are connected in sequence; the receiving end comprises a secondary side coil, a secondary side P-type topology compensation network, a rectification filter circuit, a DC-DC circuit and a battery load which are connected in sequence. The method comprises the following steps of: converting an input direct current into a high-frequency alternating current by adopting a full-bridge high-frequency inverter circuit; an LCC-P topology compensation network is set; a T-shaped equivalent model is adopted for analysis, and result information of the LCC-P topology compensation network of the wireless charging system is obtained; and a bridge rectifier circuit and a DC-DC circuit are adopted to output direct current with required amplitude, so that constant-voltage and constant-current charging is realized. According to the invention, high power and high efficiency can be maintained, constant-voltage and constant-current charging can be realized, and the cost is low.
