Description

technical field

[0001] The invention belongs to the technical field of wireless energy transmission, and in particular relates to an onboard energy storage reverse wireless power supply system and a power supply method of an unmanned aerial vehicle. Background technique

[0002] Wireless power supply technology mainly realizes non-contact power transmission through electromagnetic induction, electromagnetic resonance, radio frequency, microwave and laser. According to the different power supply distances of wireless power transmission in space, the forms of wireless power transmission can be divided into three categories: short-range, medium-range and long-range.

[0003] Among them, the one realized by electromagnetic induction power transfer technology (ICPT) belongs to short-range transmission. ICPT mainly uses a magnetic field as the medium, uses transformer coupling, and induces current through the primary and secondary coils. Electric energy can be transmitted through...
