Abstract：Magnetically coupled wireless power transfer is a new type of wireless energy transmission mode, it is also called wireless power transfer via strongly coupled magnetic resonances. After years of development, domestic and foreign scholars studying on this area have got their own achievements, but have not reached an agreement for the principle of magnetically coupled resonance yet. There are three mainly used methods of modeling at present, namely the coupled-mode theory, the scattering matrices method and electric circuit theory. In this article we establish system models separately from the coupled mode theory and electric circuit theory, then move on to the simulation and comparison. By comparative analysis on the models, we conclude that the electric circuit theory is a further interpretation on the coupled mode theory in electricity. The circuit theory can be used to explain the principle of magnetically coupled resonances wireless power transfer.
