Abstract:
The present invention increases received electrical power received by a power receiving coil by stably increasing a resonance current in the power receiving coil of a wireless power transmission system. The present invention makes use of the wireless power transmission system comprising: a power transmitting coil for generating a magnetic field via an alternating current and a power receiving coil for generating an induced voltage via electromagnetic induction of the power transmitting coil; a power receiving resonant circuit formed by connecting a resonance capacitance to the power receiving coil; a control means for controlling in which the resonance current in the power receiving resonant circuit is matched to a target value; a power receiving coil current control circuit that is controlled by the control means and applies electrical power to the power receiving resonant circuit to increase the resonance current; and a load circuit for receiving power from the power receiving resonant circuit, wherein the power receiving coil current control circuit operates by being supplied with electrical power applied to the power receiving resonant circuit from the load circuit.

Claim (Index 1):
An wireless power transmission system, comprising:\n a power transmitting coil for generating a magnetic field with an alternating current; a power receiving coil for generating an induced voltage by electromagnetic induction of the power transmitting-coil; a resonant circuit formed by connecting a resonance capacitance to the power receiving coil; a control operation unit for controlling to adjust resonance current that flows through the resonant circuit to a target value; a power receiving coil current control circuit configured to increase the resonance current by supplying electric power to the resonant circuit under the control of the control operation unit; and a load circuit configured to receive electric power from the resonant circuit; wherein the power receiving coil current control circuit, for its operation, receives electric power from the load circuit to supply thereof to the resonant circuit.
