| Abstract(in English) | As the wireless power transmission for a feeding system to electrical vehicles, a magnetic induction method with primary and secondary coils at the frequency of 80kHz or 140kHz is attractive and is widely studied in various ways. In such researches, the transmission power efficiency was discussed using the unloaded Q-factors of the coils and the coupling coefficient k between the primary and secondary coils. Such an evaluation manner using the Q-factor and coupling coefficient is usually applied in the design of filters with a relative bandwidth of about a few percent, and thus, it is desired how to evaluate the power transmission efficiency in wide frequency bands. In this report, the power transmission efficiency was formulated based on the transmission line theory and its validity was investigated in the wireless power transmission system using the magnetic induction method. |
