1. A wireless charging system for transmitting data comprises:
a charging device for wirelessly transmitting a source signal and adjusting a current value corresponding to the source signal according to a transmitted datum; and a receiving device comprising:
a first coil for receiving the source signal according to electromagnetism and accordingly generating an AC current signal; andan output module comprising:
a rectifying module, electrically connected to the first coil for rectifying the AC current signal to generate a DC current signal;a transforming module, for transforming the DC current signal into a digital signal to retrieve the transmitted datum; anda stabilizing module for stabilizing the DC current signal, comprising:
an up-loop switch, comprising an input end coupled to a power supply, an output end and a control end;a down-loop switch, comprising an input end coupled to the output end of the up-loop switch, an output end coupled to the ground and a control end;an oscillating module, comprising a capacitor and a inductor; anda stabilizing logic controller, for outputting a control signal to the control end of the up-loop switch and the control end of the down-loop switch according to terminal voltage of both ends of the inductor, so as to switch on or off the up-loop switch and the down-loop switch. |
