Title:
SIMULTANEOUS WIRELESS POWER AND DATA TRANSFER SYSTEM AND DATA MODULATION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/193371
Kind Code:
A1
Abstract:
A simultaneous wireless power and data transfer system and a data modulation method. In the method, power/information complex modulation is performed on a primary-side pre-stage converter and a secondary-side post-stage converter, and an output power/information flow can be transmitted across a wireless power transfer circuit, thus realizing communication between a primary side and a secondary side. A digital frequency band signal is modulated to a DC bus; the spectrum of a modulated digital signal is shifted to the vicinity of a power transfer frequency by using a frequency mixing effect of an inversion/rectification circuit, and the digital signal is transmitted to a different-side circuit; the different-side circuit demodulates the signal to obtain a baseband signal. The method has wide applicability, can be used for various wireless power transfer systems, and is particularly suitable for a high-frequency system.
