Abstract (in Japanese) (See Japanese page) 
(in English) Wireless Power Transfer (WPT) for Electric Vehicles (EV) is one of an admirable solution to some obstacles of charging EVs. The operation frequency, secondary resonance frequency and primary resonance frequency are assumed to be equal in the previous WPT studies. However, in real WPT system, resonance frequency mismatch occurs, when primary and secondary sides have different resonance frequencies due to inductance and capacitance
change. This paper is investigated on the power factor for the wireless power transfer systems with resonance frequency mismatch. The effectiveness of the theoretical analysis has been verified under resonance frequency mismatch condition by experimentally.
