Title:
WIRELESS POWER TRANSMISSION APPARATUS, SIGNAL PROCESSING METHOD, DEVICE AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/077623
Kind Code:
A1
Abstract:
The present application relates to the technical field of wireless power transmission. Provided are a wireless power transmission apparatus, a signal processing method, a device and a system, which are used for improving the accuracy and sensitivity of acquiring amplitude and phase information of pilot signals. The apparatus comprises a first channel and a plurality of second channels. The first channel is used for receiving a first pilot signal and outputting a reference signal according to the first pilot signal; and each of the plurality of second channels is used for receiving a second pilot signal and the reference signal and determining the phase and amplitude of the second pilot signal according to the reference signal, namely, the plurality of second channels all perform amplitude and phase identification on second pilot signals of the second channels using the reference signal outputted by the first channel according to the first pilot signal, wherein the phases and amplitudes of the second pilot signals are used for determining a power transmission signal corresponding to the second channels, and the first pilot signal and the second pilot signals are obtained by means of the first channel and the second channels receiving the same pilot signal.
