The invention provides a bidirectional wireless charging system of a hydrogen-electricity hybrid power unmanned aerial vehicle and a control method. The system comprises an isolation type three-port full-bridge DC/DC converter, a multiplexed magnetic coupling mechanism and compensation topology, a switch switching matrix, a control signal unit, a driving signal unit and a wireless communication module. The wireless charging technology has the core advantages of physical isolation, safety, reliability, high environmental adaptability and the like, ignition can be effectively prevented, a lithium battery does not need to be manually replaced, and automatic electric energy supply is achieved. The bidirectional wireless charging system of the unmanned aerial vehicle multiplexes the three-port DCDC converter in a time-sharing manner, so that the utilization rate of the converter is improved, the flexibility of the system is improved, the weight of the system is greatly reduced, the load is reduced, and the cruising ability of the unmanned aerial vehicle is improved.
