Use coupled mode theory, for the resonator system being made up of transmitting coil and receiving coil, if field intensity α in two coils1(t) and α2T (), can be determined by below equation group:
In formula, ω1、ω2It is respectively transmitting coil and the characteristic frequency of receiving coil, Γ1、Γ2Being respectively transmitting coil and the natural attenuation rate of receiving coil, k is the coefficient of coup between two coils, and wherein the biggest coupling of k is the strongest, and energy transmission efficiency is the highest.When coupling efficiency is far longer than attenuation rate, i.e.Time, it is lost less, energy can high efficiency of transmission.
2, resonance coupling model
As it has been described above, be the most only modeled system generation magnetic coupling resonance portion, its energy transmission system model is set up as shown in Figure 3.
In figure, Us is the equivalent inpnt power supply of transmitting coil, and it is the mixed signal of transmitting terminal energy signal and information signal, R1、R2For coil equivalent ohmic resistance, L1、L2For coil equivalent inductance, C1、C2For coil equivalent capacity, M represents the mutual inductance between two coils, RLFor equivalent load.If the angular frequency of transmission system is that the electric current in ω, transmitting coil and receiving coil is respectively i1And i2, near field region, the distance on two coil central axes is d, that is transmission range is d, thus, can show that the impedance loop of transmitting coil and receiving coil is:

In formula, μ0For permeability of vacuum；σ is electrical conductivity, and l is coil total length, and a is winding wire radius, and r is coil radius, and n is coil turn, ε0For dielectric constant of air, h is coil width, and c is the light velocity.
For the wireless power transmission systems of moderate distance resonance coupling, its optimal self-resonant frequency is generally 1MHz～50MHz, scattering resistance typically at the 10-4 order of magnitude, so time have Rr R0, the most negligible radiation resistance, then R1=R2=R=R0, additionally, due to the calculating of mutual inductance is more complicated, use Approximate Equivalent to calculate here, finally can obtain system effectiveness η is:
From formula, in the case of coil parameter is fixing, system effectiveness is inversely proportional to 6 powers of distance.In practical operation, actual value substantially conforms to theoretical value, lower than theoretical value, mainly have ignored resistance loss, radiation loss etc. when Theoretical Calculation, and judge to be in resonant condition according to receiving-end voltage value maximum during practical operation, exist certain error, Theoretical Calculation is in the most Utopian state, the actual impact also having parasitic parameter etc., therefore experiment value is less than theoretical value.
