磁耦合諧振式無線電能傳輸方向性分析與驗證
[Abstract]:In order to solve the problem whether the angle deflection will affect the receiving electric energy in the magnetically coupled resonant radio energy transmission system, the frequency characteristics of the radio energy transmission system are analyzed by using the mutual inductance coupling theory of two hollow coils in space and the equivalent circuit. The frequency response curve of normalized voltage and the necessary condition of wireless power transmission are obtained. Then, according to the relationship between the coupling coefficient and the direction of the hollow coils placed arbitrarily in space, the directional characteristics of the system under the three states of over-coupling, critical coupling and under-coupling are proposed. Finally, the experimental circuit is designed and the related experimental research is carried out. The experimental results are in good agreement with the theoretical analysis, which verifies the directional problem in the radio energy transmission system. The analysis of directionality in this paper provides a useful reference for the design of radio energy transmission system and parameter optimization of mobile equipment.
