APPARATUS FOR SUPPLYING POWER TO ELECTRONIC DEVICES BY USING WIRELESS POWER TRANSMISSION MODE

摘要

PURPOSE: An apparatus for supplying wireless power to electronic devices in a vehicle is provided to prevent an accident by not directly connecting a connection jack to a receiving device. CONSTITUTION: An AC signal generator generates an AC signal of a preset frequency. An electromagnetic field generator generates an electromagnetic field by receiving an AC signal from the AC signal generator. A charger is installed in an electronic device(230) to charge voltages via a rectifier. A transmission coil(210) generates induced electromotive force by an electromagnetic induction with regard to the electromagnetic field from the electromagnetic filed generator. A relay amplifier(220) amplifies an electromagnetic field weakened by wireless transmission.
