Research on Wireless Power Megnetic Flux Leakage Based on Particle Swarm Magnetic Field Editing Algorithm
Maintaining high efficiency and power in a wireless power transfer system can lead to a significant increase in the magnetic flux leakage of the system.For this reason the paper proposes a multi-coil transmitting system applied to unmanned aerial vehicle(UAV)wire-less power transfer system,which reduces the magnitude of magnetic flux leakage on the target observation surface while maintaining the transmission efficiency and output power.Firstly,based on a method for calculating the magnetic field density of a square coil and proposes a magnetic field editing technique,which can be utilized to change the magnetic field strength at the target location.Secondly,the magnetic field editing algorithm is combined with an improved particle swarm algorithm to enable the control section to control the system in a larg-er dimension.Finally,a wireless charging system for UAVs with multiple transmitting coil arrays is proposed,and the simulation analysis shows that the proposed system maintains the maximum leakage in the target area at 5 μT and the transmission efficiency is as high as 96.7%when the output power of the system is kept at a constant level of 200 W.
