METHOD FOR CONTROLLING RECEIVING VOLTAGE FOR DEVICE TO BE POWERED BY WIRELESS POWER TRANSMISSION, WIRELESS POWER TRANSMISSION DEVICE ADJUSTED BY METHOD FOR CONTROLLING RECEIVING VOLTAGE, AND METHOD FOR MANUFACTURING WIRELESS POWER TRANSMISSION DEVICE

摘要

A method for controlling a receiving voltage whereby a receiving voltage applied to a device to be powered by adjusting the capacitance and so forth of a circuit element provided in the wireless power transmission device, a wireless power transmission device adjusted by the method for controlling a receiving voltage, and a method for manufacturing the wireless power transmission device. This method controls a receiving voltage for a device to be powered when power is supplied from a power supply module that constitutes a wireless power transmission device to a power receiving module with a magnetic field being changed and the supplied power is fed to the device to be powered connected to the power receiving module. The driving frequency for the power supplied to the power supply module is not a resonant frequency in the power supply module and the power receiving module.

1. A method for controlling a receiving voltage to a device to be powered by a wireless power transmission apparatus, wherein the wireless power transmission apparatus configured to supply power from a power-supplying module to a power-receiving module by varying a magnetic field, and supply that supplied power to the device to be powered connected to the power-receiving module,
the power is supplied with a value such that a driving frequency of the power supplied to the power-supplying module does not match with a resonance frequency between the power-supplying module and the power-receiving module, and element values of a plurality of circuit elements of the power-supplying module and the power-receiving module are used as parameters and varied to adjust the receiving voltage to the device to be powered.
