Annex Wireless Charging Coil Design Parameters UAV Introduction

Abstract

Based on the coupling coefficient, quality factor and structure of the planar spiral coil better than that of the cylindrical spiral tube, a magnetic resonance resonant wireless charging system is established. The effects of coil transmission efficiency, coil turns, coil inner diameter, coil outer diameter and coil spacing on coil transmission efficiency are calculated. The influence of mutual inductance, M and coil equivalent internal resistance is analyzed deeply.
