摘要：
In order to confirm whether the frequency offset will influence the maximum output-power or efficiency of load in electric-field coupled power transfer (ECPT) system, the circuit model of the ECPT system was studied with the help of the impedance transformation principle. The calculation method to transfer power and its efficiency was proposed. And there are two results through theoretical analysis. One is the inconsistency on maximum output-power and efficiency with the frequency offset and the other is the maximum power is obtained when the normal frequency is slightly less than 1. In the end, experiment device was designed and experimental results were well consistent with the theoretical analysis, which shows correctness of the proposed method and its result. © 2019, Harbin University of Science and Technology Publication.
