[0002] At present, the power of the UAV is provided by the on-board battery. The larger the battery, the greater the load on the UAV, and the longer the flight time, the more power it needs. Its load causes more waste of electric energy

[0003] Airborne power generation equipment has not yet been applied in the field of UAVs, and the airborne power generation devices used in existing aviation equipment are usually heavy in weight and large in size, which is difficult to be directly applied to UAVs, and the generated voltage is unstable. This caused the communication of the autopilot to be greatly affected

Due to the instability of various parameters sent, it is easy to cause confusion of various data parameters, which affects the effect and quality of the drone's ground control and aerial photography

Moreover, due to the limited battery capacity of the current UAV, there are more and more electronic devices in the aircraft, the problem of power supply of electronic devices, and the problem of flight endurance can no longer meet the needs of multi-power, full-electricity and long-term flight of UAVs. It will be more difficult to provide enough power for the aircraft to fly directly from the limited battery of the aircraft
