Wireless Power Transfer System for an Unmanned Aerial Vehicle

An Inductive Power Transfer (IPT) system that can wirelessly charge an Unmanned Aerial Vehicle (UAV) is proposed. The IPT system is modelled such that it can be used to charge the DJI Mavic Pro. The receiver (Rx) coil is designed according to the dimensions of the drone. The transmitter (Tx) coil is a circular planar coil. The system uses a Series - Parallel (S-P) compensation network. The design and simulation done with the aid of finite element analysis software, ANSYS Maxwell. An equivalent circuit is simulated on LT Spice to determine its efficiency. The efficiency of the proposed system is verified experimentally.
