Title:
VOLTAGE OPTIMIZATION JOINT CONTROL METHOD FOR USE IN MULTI-MODULE WIRELESS CHARGING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/217054
Kind Code:
A1
Abstract:
A voltage optimization joint control method for use in a multi-module wireless charging system is disclosed. The multi-module wireless charging system comprises a plurality of wireless charging modules, and each wireless charging module comprises a transmitting coil, a receiving coil, a transmitting end circuit and a receiving end circuit; the output sides of all the wireless charging modules are connected in parallel, such that said modules output a same load; each of the wireless charging modules uses an LCC compensation topology, the total output current of the multi-module wireless charging system is used as a feedback quantity, the reference input voltage of the multi-module wireless charging system is controlled, and the input voltage amplitude of each wireless charging module is adjusted on the basis of an input voltage amplitude ratio matrix, thus achieving output control and current equalization in the multi-module wireless charging system. The present invention has good universal applicability.
