Determining an optimum layout transferring and receiving coils is very important for electromagnetic field resonance type wireless power transfer, in order to obtain target receiving power or efficiency. In this paper, an approach for identifying a coil layout for electromagnetic field resonance type wireless power transfer is proposed. First, a simulation model of coil layout identification has been described. Second, the proposed approach has been applied to identifying an optimum layout of flux phase‐shifter coils between transferring and receiving coils, when receiving currents are achieved to target currents. Also, the proposed approach has been applied to identifying an optimum layout of flux phase‐shifter coils between transferring and receiving coils, when efficiency is achieved to target one. Further, the approach has been applied to identifying a layout of flux phase‐shifter coils, when three receiving currents were balanced three phase currents. As a result, the identified results have been verified the validity of the approach.
