Design and Development of Wireless Power Transfer System for UAV

摘要

Wireless magnetic resonant power transfer is an emerging technology which has many advantages over the other Wireless Power Transfer (WPT) methods due to lack of interference, its efficiency for medium ranges and safety. This paper proposes the WPT applications for charging the battery of electric powered Unmanned Air Vehicles (UAV). Depending upon the flight path of the UAV and estimated power, the coils are designed and developed. These operate as a wireless power transferring system at high frequency of 63.5 KHz with a gap of 60mm between the two coils. In this paper, the concepts referred for the design and analysis for WPT system has been presented. This has been achieved using magnetic resonant coupling with two coil WPT system using SS topology. The analysis has been carried out using results from simulations and hardware experiments which can be used for the selection of battery required for the UAV and also the selection of components of UAV depending upon the particular application.
