Title:
WIRELESS POWER RECEIVING APPARATUS FOR CARRYING OUT IN-BAND COMMUNICATION WITH WIRELESS POWER TRANSMITTING APPARATUS AND METHOD FOR CARRYING OUT IN-BAND COMMUNICATION IN WIRELESS POWER RECEIVING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/203253
Kind Code:
A1
Abstract:
According to various embodiments, a wireless power receiving apparatus comprises: a resonance circuit configured to receive wireless power from a wireless power transmitting apparatus; a plurality of first capacitors; a plurality of first switches; a plurality of second capacitors; a plurality of second switches; a rectifier circuit connected to a first end and a second end of the resonance circuit; and a control circuit connected to the rectifier circuit, wherein first ends of the plurality of first capacitors are each connected to the first end of the resonance circuit, second ends of the plurality of first switches are respectively connected to first ends of the plurality of first switches, second ends of the plurality of first switches are connected to ground, first ends of the plurality of second capacitors are each connected to the second end of the resonance circuit, second ends of the plurality of second capacitors are respectively connected to first ends of the plurality of second switches, and second ends of the plurality of second switches are connected to the ground, and the control unit may be configured to select, on the basis of a CEP value identified on the basis of an output of the rectifier circuit, switches for modulating data to be transmitted to the wireless power transmitting apparatus, among the plurality of first switches and the plurality of second switches, and control on/off of the selected switches on the basis of modulation of the data. Various other embodiments are possible.
