Title:

DYNAMIC WIRELESS POWER TRANSMISSION OUTPUT POWER CONTROL METHOD BASED ON SLIDING MODE PREDICTION CONTROL

Document Type and Number:

WIPO Patent Application WO/2023/193649

Kind Code:

A1

Abstract:

The present invention belongs to the technical field of wireless power transmission. Disclosed is a dynamic wireless power transmission output power control method based on sliding mode prediction control. The method is applied to an LCC-S-type resonant circuit, and can keep an output voltage stable during a dynamic process, maximize an output power of a magnetically coupled resonant wireless power transmission system, and perform control simply by sampling a load voltage and an inductive current. On the basis of a sliding mode prediction controller in the method of the present invention, feedback self-correction of sliding mode control can be realized. Compared with a conventional controller, the controller, which is realized by means of the method of the present application, is more accurate and faster in both a transient environment and a steady-state environment. The controller is based on a new prediction control algorithm under a certain condition, thereby widening the available working range of a system, and ensuring the reliability of a wireless charging system under a dynamic change in a coupling coefficient within a large range.
