  Drones are increasingly operating autonomously, and the need for extending
drone power autonomy is rapidly increasing. One of the most promising solutions
to extend drone power autonomy is the use of docking stations to support both
landing and recharging of the drone. To this end, we introduce a novel wireless
drone docking station with three commercial wireless charging modules. We have
developed two independent units, both in mechanical and electrical aspects: the
energy transmitting unit and the energy receiving unit. We have also studied
the efficiency of wireless power transfer and demonstrated the advantages of
connecting three receiver modules connected in series and parallel. We have
achieved maximum output power of 96.5 W with a power transfer efficiency of
56.6% for the series connection of coils. Finally, we implemented the system in
practice on a drone and tested both energy transfer and landing.
