Abstract

In order to study the theoretical research of electromagnetic coupling resonance wireless transmission technology, the model was established by coupling theory and circuit theory respectively. By studying the transmission characteristics of power and efficiency, the parameters of the system, the relative position of the coil, and the transmission medium, the power transmission was achieved by electromagnetic coupling resonant transmission technology efficiently and stably. Through model analysis and MATLAB and PSpice simulation analysis, the effects of coil natural frequency, mutual inductance and coupling coefficient, transmission distance, load and coil parameters on the transmission characteristics of the system were studied. The phenomenon of frequency division and its causes were discussed. The optimal power natural frequency fp, the best power mutual inductance Mp, the best power load Rp, the best efficiency load Rη, and the optimum power distance dp were obtained. It provided the basis for system optimization design. The corresponding scheme was proposed for the optimization design of electromagnetic resonance coupled wireless transmission system with different requirements. The hardware design of the system was introduced in detail. The experiment device was made by the hardware circuit design. Through a series of experimental data analysis, the factors affecting the transmission characteristics of magnetically coupled resonant wireless transmission technology were analyzed. The results show that as the transmission distance increased, the system's optimal output power and optimal transmission efficiency were reduced. The distance between the best power load and the best efficiency load was decreasing. Therefore, this method can obtain a high frequency power supply that satisfies the resonance frequency.
