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.
