摘要：
In wireless power transfer (WPT), resonance frequency mismatch occurs, when primary and secondary sides have different resonance frequencies due to inductance and capacitance change. This paper examines on the transmission efficiency of the WPT systems, those are influenced by the resonance frequency mismatch. It is proved that the transmission efficiency is influenced by the operating source frequency and secondary resonance frequency, and not lean on the primary resonance frequency, by conducting both the logical analysis and the experiment. Furthermore, transmission efficiency maximization of WPT system with resonance frequency mismatch is proposed by optimizing the load resistance in this paper. In addition, the validity of the proposed method was confirmed by numerical simulation and experiment.
