Circuit Model Based Analysis of a Wireless Energy Transfer System via Coupled Magnetic Resonances
Open accessAbstract
자기공명을 이용한 무선 전력 전송 시스템의 등가회로 모델이 제시되었고, 이를 통한 설계기법이 제안되었다. 두개의 코일로 구성된 간단한 트랜스포머의 등가회로를 확장하는 방법으로 본 시스템의 노드 방정식을 세웠고, 이로부터 효율을 높이기 위한 최적의 코일간 거리를 해석하였다. 손실이 있는 경우의 주파수 특성을 계산하기 위해, 상용 설계 시뮬레이터에 등가회로 모델을 심었다. 실제 시스템의 모델 파라미터를 추출하여 시뮬레이션 결과와 측정결과를 비교하였다. 이 해석으로부터, 자기공명 방식의 무선 전력 전송 시스템이 수 미터의 거리까지 높은 효율을 보일 수 있음을 알 수 있었고, 이때 임피던스 정합이 매우 중요하다는 것을 알 수 있었다. 개발된 모델을 통해 공진 코일이 더 많이 있는 경우와 같은, 유사한 시스템의 특성을 예측할 수 있다. A Simple equivalent circuit model is developed for a wireless energy transfer system via coupled magnetic resonances and a practical design method is also provided. Node equations for the resonance system are built with the method, expanding on the equations for a transformer, and the optimum distances of coils in the system are derived analytically for optimum coupling coefficients for high transfer efficiency. In order to calculate the frequency characteristics for a lossy system, the equivalent model is established at an electric design automation tool. The model parameters of the actual system are extracted and the modeling results are compared with measurements. Through the developed model, it is seen that the system can transfer power over a mid-range of a few meters and impedance matching is important to achieve high efficiency. This developed model can be used for a design and prediction on the similar systems such as increasing the number of receiving coils and receiving modules, etc.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
