Abstract (in Japanese) (See Japanese page) 
(in English) A mid-range energy transfer experimental system having two auxiliary resonant circuits is analyzed. In this system, one resonant circuit is closely coupled to the input coil and the other is to the output coil feeding power to a load in the operating frequency around 25 kHz. In the analysis, magnetic coupling between all the coils (four coils) are taken into consideration. Coupling coefficient calculated for a pair of one-turn ring coils is used to estimate mutual inductances, namely the coil height of multi-turn solenoidal coil is assumed to be zero (diameter of the coil conductor is neglected). Three specific distances between the input coil and the first resonant coil (d1), between the first and the second resonant coil (d2) and between the second resonant coil and the output coil (d3), and normal circuit parameters are fully taken into consideration. Transferred energy and the efficiency of transferring are calculated for a set of given conditions. Also analyzed are magnetic flux density distributions on the axis of coil system for a series of the phase angle (ωt) of a sinusoidal power source, which visualize energy transferring.
