Abstract
Wireless power transfer systems using electric fields have been investigated mainly for power transfer over extremely close regions. Using an electromagnetic field simulator, we have made a prototype of an LC series type resonance coupler made from a coil and electrode. When the distance between the transmission and reception couplers was varied, it was found that a transfer efficiency of 90% or more was achieved at a distance of 180 mm. Also a large power transfer test was carried out in which it was found that it was possible to transfer 838 W of power.
