Wireless charging pad, which is a key design part of the inductive power transfer (IPT) system, has high voltage and current characteristics, and since resulting losses account for the largest proportion of the entire system, an accurate experimental verification should be required. This paper proposes a method to obtain the same wireless charging pad voltage and current stress in a limited test environment by reconfiguring the resonant network of the IPT system. The proposed method allows experiments in a limited laboratory environment by flexibly designing input/output characteristics. The validity of the proposed method is verified through a 2-kW prototype experiment.
