Electromagnetic energy harvester design, optimization and application for unmanned aerial vehicles

Parallel to the increase in energy demand, the importance of energy transmission lines is also increasing. In order for energy transmission to be carried out correctly, transmission lines must operate uninterruptedly. Therefore, it is important to inspect and monitor the lines and to intervene immediately in case of any fault. The use of Unmanned Aerial Vehicles (UAV) for the inspection and monitoring of these lines provides advantages in terms of both safety and cost. In the study, the design and analysis of electromagnetic energy harvesters have been made in order to provide energy to UAVs. Firstly, the mathematical modeling of the core has been presented. Electromagnetic energy harvesters designed based on this model have been analyzed using the Finite Element Method (FEM). Then, the experimental setup was set up and the performance of the harvesters was also examined in the experimental environment. With the results obtained from SEM analyzes and experiments, the performances of electromagnetic energy harvesters consisting of various structures and materials according to size, material properties, air gap and line current variables were examined and the harvester with the best size / energy density was tried to be revealed.
