Abstract(in English) Using the principle of the magnetic resonance coupling, the efficiency of the energy transfer in a mid-range has been reported. In this report, a new method using two resonant circuits separately prepared from the input and the output circuit is proposed to transfer power in an operating frequency over 20kHz. Dependences of the efficiency of the power transfer on the distance and that and on the operating frequency were examined. In addition, phases of the voltage and the current in the primary, and the behavior of the magnetic field carrying power between two resonant circuits were observed. Energy was transferred at efficiency 78.7% at the distance 15cm, and at efficiency 75.5% at the distance 20cm with an input and an output coil of diameter 20cm.
