Short Range Wireless Power Transfer (WPT) for UAV/UAS Battery Charging - Phase 1

Abstract

The inductive and radiative approaches to wireless power transmission (WPT) were simulated using commercial software. For the inductive approach, working at 100 kHz, efficiencies over 90% were obtained at short ranges (less than 30 mm) utilizing ferrite plates. For the radiative approach, the transmission loss between antennas was less than 1 dB at ranges less than 3 m when near field focusing was employed. The results for the two approaches are important because they demonstrate that efficient transmission of energy for battery charging can take place between a WPT ground station and client.
