Document Type and Number:
WIPO Patent Application WO/2023/109333
Kind Code:
A1
Abstract:
Provided in the present application are a power supply end, a wireless power supply system, a power supply method, and a computer storage medium, which can improve the wireless power supply efficiency. The power supply end comprises a transceiver and a plurality of radiation circuits. The transceiver is used for generating a charging signal, which comprises electromagnetic waves of at least one frequency band, and respectively providing the charging signal for the plurality of radiation circuits; each of the plurality of radiation circuits can transmit electromagnetic waves of one or more target frequency bands, the plurality of radiation circuits comprise a first radiation circuit and a second radiation circuit, and one or more target frequency bands included in the electromagnetic waves which are transmitted by the first radiation circuit are different from one or more target frequency bands included in the electromagnetic waves which are transmitted by the second radiation circuit; and each of the plurality of radiation circuits is used for filtering the charging signal, and if a target electromagnetic wave is filtered out, transmitting the target electromagnetic wave, wherein the frequency band corresponding to same is included in one or more target frequency bands corresponding to the electromagnetic waves which can be transmitted by the corresponding radiation circuit.
