Three-Phase Magnetic Field Design for Low EMI and EMF Automated Resonant Wireless Power Transfer Charger for UAV
Wireless power transfer (WPT) technology enables convenient and automatic battery charging for unmanned aerial vehicles (UAVs). However, in WPT charging systems, strong electromagnetic fields (EMFs) are inevitably generated and the power source contains a wide range of harmonics. In this paper, we propose an automated resonant wireless power transfer charger for UAV with three-phase magnetic field for electromagnetic interference (EMI) and EMF reduction. The simulation results show that the proposed six-step three-phase resonant WPT system for UAV charging reduces the total harmonic distortion (THD) of the Tx and Rx currents by 14.21% and 7.45%, respectively. The strength of magnetic field from the UAV three-phase resonant WPT charging system also can be reduced compared to the single-phase resonant WPT system.
