Magnetic coupling resonance principle to design a wireless power transmission device based on 12V, 10W, lighting load power supply. The experimental device comprises a DC power supply module, inverter module, coupling coil, capacitor, and high frequency rectifier The success of light load circuit, lighting, realizes the wireless power transmission. Using MATLAB simulation that the frequency, resonant frequency, transmission distance, mutual inductance, load impedance influence on the transmission performance of the system, necessary condition and frequency analysis of resonance splitting phenomenon; frequency characteristic, research system through experiments of coupling, distance and penetration the results, to verify the theoretical analysis and simulation. The frequency tracking control method of the system, by setting different closed loop circuit of the system, to solve the frequency detuning brings adverse effects, ensure the system has better transmission characteristics. This paper designed can transfer experimental device of magnetic coupled resonant wireless. The success of 12V lights, 10W lighting load, and transmission characteristics were studied by simulation and experiment on the system, the result of the research and practice of follow-up Guiding significance.
