Abstract


With the electricity extensive used, since many people are dreaming get rid of the burden ofthe wire line and wireless energy transfer has been only as a dream. Wireless energy transfer ornon-contact energy transfer refers to a process that the energy from the power source throughwireless transfer to the load, different from wire transfer energy daily.First, the paper analyze improving the wireless energy transfer efficiency of the twoelements ,one is launch coil and receive coil resonance ,the other is the coupling coefficient oftwo wire coils far outweigh the losses parameters of 1, namely two wires strong coupling. Andcalculating the resonant frequency, coupling coefficient, coil parameters such as the loss of theimpact of these parameters. then analyzes the factors such as the resonance of coil radius, circlenumbers and two coils distance etc.In order to improve the transfer efficiency of the energy system make energy more usereasonably and for greater distance, the paper in two wire transfer of energy theory is proposed,based on and derived two special circumstances and calculate the propagation of the energeticchanges each coil.This topic research will solve the mid-range energy transfer problems which based on theWitricity technology of wireless energy transfer .In the future of everyday life it will havefar-reaching significance and the broad application prospect.
