Abstract:At present, there are three main principles of wireless power transmission technology: electromagnetic induction coupling principle, the principle of magnetic resonance coupling and the principle of microwave radiation coupling。 This paper analyzes and compares the advantages and disadvantages of the three kinds of transmission principle, and the principle of magnetic resonance coupling is chosen as the theoretical basis of this paper。 Compared with other transmission principle, the method of magnetic resonance coupling transmission has higher transmission efficiency, moderate transmission distance and transmission power。 This paper first from the near field theory, the resonance theory, two resonant circuit analysis start, summed up a series of formulas and expressions, which more important is transmission efficiency expression, transmission efficiency expression, research on power efficiency and frequency, coupling coefficient and frequency provides a basis and analysis obtained maximum transmission efficiency and the maximum transmission power, makes an upholstery for the following analysis and design, the final design of a small wireless power transmission device。
Keywords:Wireless power transmission, magnetic resonance coupling, transmission power, transmission efficiency
