This paper proposed EMI reduction method for over-coupled wireless power transfer (WPT) system using series-none (SN) topology. The series-none (SN) topology does not has the compensation capacitor for minimizing reactive power of receiver side. The proposed topology has higher input impedance than conventional series-series (SS) topology, resulting in the odd harmonic components of current for SN topology has lower than that of SS topology. In addition, when the over-coupling phenomena occurs, there is not much difference in efficiency of transferring power compared to SS topology. The proposed method is verified through the 3D EM tool and circuit simulation.
