ELECTRICITY SUPPLY MODULE USING WIRELESS POWER TRANSMISSION AND POWER SUPPLY METHOD OF ELECTRICITY SUPPLY MODULE

摘要

A power-supplying module and a power-supplying method for the power-supplying module, by which power consumption of the power-supplying module is reduced without providing an additional device, when the power-supplying module and a power-receiving module are not in a power-suppliable region (i.e., in a standby state) are provided. A power-supplying module which is connected with a AC power source and supplies power to a power-receiving module by utilizing a resonance phenomenon is driven at a power-source frequency in which an input impedance Zin of the power-supplying module in a standby state is higher than an input impedance Zin of the power-supplying module and the power-receiving module in a power-supplying state.

1. A power-supplying module for supplying power from the power-supplying module connected with a power source to a power-receiving module by utilizing resonance phenomenon, the power-supplying module being driven at a power-source frequency of the power source so that an input impedance of the power-supplying module in a standby state in which no power is supplied from the power-supplying module to the power-receiving module is higher than an input impedance of the power-supplying module and the power-receiving module in a power-supplying state in which the power is supplied from the power-supplying module to the power-receiving module.
