Abstract:
In a wireless power transfer system, a resonant circuit is formed on the secondary coil side, phase information of a resonant current flowing in the resonant circuit is detected, and, based on this phase information, a driving frequency is determined so that the current phase of a driving current flowing in a primary coil slightly delays from the voltage phase, thereby driving the primary coil. A Q value determined based on a leakage inductance of the secondary coil, a capacitance of a resonant capacitor, and an equivalent load resistance is set to a value greater than or equal to a value determined by Q=2/k 2  (k is a coupling coefficient).

Claim (Index 11):
The wireless power transfer system according to  claim 8 , wherein the resonance current phase detection means detects the phase information from a current flowing through a small-capacity capacitor connected in parallel to the resonance capacitor.
