Bibliography:Study the magnetic coupling resonant system based on the equivalent circuit of coil and the coupled-mode theory first.The formulas are derived to calculate the transmission efficiency parameter of wireless power transmission system. Then a simulation using MATLAB programming is established to analysis the theoretical efficiency graphics. Finally, design a circular spiral magnetic coupling coil model using electromagnetic simulation software HFSS. We get the effect of energy transfer efficiency of the system by changing the distance of transmission coil and adding a relay resonant coil based on the simulation of the model. Results show that it can extend the transmission distance and improve the efficiency of transmission by adding a relay resonant coil. Although there are some errors, the simulation results are consistent with the theoretical analysis.
