IEM(임피던스 확장 방법)은 모멘트 방법을 기반으로 하는 전기적 소형 장치의 회로 모델링 기술입니다. 이전 연구에서는 IEM과 고유모드 분석을 활용하여 무선전력전송(WPT) 시스템의 회로 모델을 개발하였다. 그러나 이 기술은 모든 결합 요소(예: 급전 루프 및 공진 코일)가 이웃 산란(예: 차량 차체)이 없다고 가정합니다. 본 연구는 IEM의 이론을 확장하여 PCS(완전 전도성 산란기) 근처에서 WPT 시스템의 회로 모델을 얻습니다. 수치 결과는 제안된 방법이 PCS의 크기가 약 XNUMX/XNUMX 파장보다 작은 주파수에 적용될 수 있음을 보여줍니다. 또한, 산출된 회로 모델은 동작 주파수 대역에서 유효한 것으로 나타났다.

Abstract: The impedance expansion method (IEM) is a circuit-modeling technique for electrically small devices based on the method of moments. In a previous study, a circuit model of a wireless power transfer (WPT) system was developed by utilizing the IEM and eigenmode analysis. However, this technique assumes that all the coupling elements (e.g., feeding loops and resonant coils) are in the absence of neighboring scatters (e.g., bodies of vehicles). This study extends the theory of the IEM to obtain the circuit model of a WPT system in the vicinity of a perfectly conducting scatterer (PCS). The numerical results show that the proposed method can be applied to the frequencies at which the dimension of the PCS is less than approximately a quarter wavelength. In addition, the yielded circuit model is found to be valid at the operating frequency band.
