Traditional metal contact directly powered by electricity transmission, there is a sliding abrasion, contact with sparks, insecurity and other risks exposed conductor. In order to improve the shortcomings of the traditional wire circuit power transmission, this paper designed a short distance wireless power transmission system. It overcomes many shortcomings of traditional methods of power transmission, in some flammable, explosive, humid special environment, without contact, complete and efficient transmission of electrical energy. This paper introduces the realization of wireless power transmission in three ways, compare and select magnetically coupled resonant wireless power transmission achieved. Based on a detailed analysis of the theory of coupled model is magnetically coupled resonant wireless power transmission works, deduced by calculating the energy transfer efficiency of the system to improve the formula. The system consists of a power supply circuit, high-frequency inverter circuit transmitting and receiving coils, composed of severa
