TRANSMITTING DEVICE, WIRELESS CHARGING SYSTEM COMPRISING TRANSMITTING DEVICE, AND METHOD FOR CONTROLLING CHARGING PROCESS THEREOF

摘要

A transmitting device, a wireless charging system comprising the transmitting device and a method for controlling a charging process of the wireless charging system are provided. The transmitting device comprises: a transmitting coil configured to transmit an electric energy of the transmitting device; an oscillation and FM module configured to generate an LC resonance between the transmitting coil and the oscillation and FM module and to adjust a capacitance of the LC resonance so as to change a resonant frequency of the LC resonance; a first detecting module configured to detect a voltage and a current of the transmitting device; a control module configured to output a control signal to control the resonant frequency of the LC resonance according to a predetermined FM mode; a first communicating module configured to communicate with the receiving device wirelessly; and a power module configured to supply a drive power to the transmitting device.
