电场耦合无线功率传输通常使用电路模型进行分析。然而，这种模型的电路行为并不一定是显而易见的，因为它们的谐振模式可能比基本的LCosillation复杂得多。本文提出了一种新的等效电路的基本无线电力传输系统解决这个问题。该等效电路具有比传统电路模型更简单的拓扑结构。此外，等效电路允许直观地理解三种类型的谐振模式。沿着对所提出的等效电路进行了理论推导，并给出了仿真结果，验证了等效电路的合理性。© 2015日本电气工程师协会。出版社：John Wiley & Sons，Inc.
Electric‐field coupling wireless power transfer has been commonly analyzed using the circuit model. However, the circuit behavior of this model is not necessarily apparent because their resonant modes can be far complicated than the basicLCoscillation. This issue is addressed in this paper by proposing a novel equivalent circuit for a basic wireless power transfer system. This equivalent circuit has a simpler topology than the conventional circuit model. Furthermore, the equivalent circuit allows intuitive understanding of three types of the resonant modes. Along with theoretical derivation of the proposed equivalent circuit, this paper also presents simulation results, which verified the appropriateness of the equivalent circuit. © 2015 Institute of Electrical Engineers of Japan.
