  • Publication number: 20150311742
    Abstract: In the wireless power transmission apparatus, in which power is supplied by resonance phenomenon from a power-supplying module to a power-receiving module that is connected to a lithium ion secondary battery capable of being charged by a constant current/constant voltage charging system, a variable parameter, which constitutes the power supply module and the power receiving module, is set such that the transmission characteristic value for the drive frequency of power supplied to the power-supplying module exhibits double-hump characteristics. Thus, adjustment of the drive frequency sets the variation tendencies of the input impedance of the wireless power transmission apparatus during constant voltage charging to adjust the variation tendencies of the input current of the wireless power transmission apparatus, and enables the heat generated by the wireless power transmission apparatus to be controlled.

  • Publication number: 20150263529
    Abstract: In the present invention, the power consumption of a power-supplying module is reduced in the case (standby state) that the power-supplying module and a power-receiving module are not in a power-suppliable region without providing a new device while suppressing the strength of a magnetic field generated in the vicinity of the power-supplying module and the power-receiving module. The wireless power transmission apparatus is such that the power-supplying module, which supplies power using a resonance phenomenon to the power-receiving module from the power-supplying module connected to an AC power source, is operated at a power source frequency such that the input impedance of the power-supplying module in a standby state in which a magnetic field space is not formed is greater than the input impedance of the power-supplying module and power-receiving module in a power-supplying state in which a magnetic field space is formed.

  • Publication number: 20150263530
    Abstract: A wireless power transmission apparatus 1 includes a power-supplying module 2, a power-receiving module 3, a phase detector 4, and a control device 5, and is set so that its transmission characteristic with respect to the power-source frequency has a double-hump characteristic. The control device 5 determines whether to supply power to the power-supplying module 2, based on variation in the phase of the input impedance Zin in the power-supplying state and that in the standby state, which is detected by a phase detector 4.

  • Publication number: 20150229163
    Abstract: An arrangement place for a device such as a rectifier and a power storage device is easily secured. At the time of power supply using a resonance phenomenon, a power-receiving device generates a magnetic field space having a lower magnetic field strength than other parts at or around the inner side of the power-receiving module, and this magnetic field space is used as the arrangement place of an electronic component. The power-receiving module includes a power-receiving resonance coil which is resonated with a power-supplying module and a power-receiving coil which partly overlaps the power-receiving resonance coil in a coil diameter direction and receives and supplies power from and to the power-receiving resonance coil.

  • Publication number: 20140325830
    Abstract: By supplying power from the power-supplying resonator to the power-receiving resonator by means of resonance, an electromagnetic space having a relatively low magnetic field strength is formed between the power-supplying resonator and the power-receiving resonator. In so doing, the position where the electromagnetic space is formed is changed by setting the frequency of the AC power supplied from an AC power source to the power-supplying module to an antiphase resonance mode or an inphase resonance mode, and the size of the electromagnetic space is changed by changing the distance between the power-supplying coil and the power-supplying resonator and the distance between the power-receiving resonator and the power-receiving coil.
