Title:
WIRELESS CHARGING SYSTEM CONTROL CIRCUIT AND METHOD FOR CONTROLLING RECTIFIER MODE VIA HARD WIRE
Document Type and Number:
WIPO Patent Application WO/2023/184659
Kind Code:
A1
Abstract:
The present invention provides a wireless charging system control circuit and method for controlling a rectifier mode via a hard wire. The wireless charging system control circuit comprises a rectifier mode control signal generation circuit, the rectifier mode control signal generation circuit being connected to a rectifier of a receiving end of a wireless charging system by means of a rectifier bridge driving circuit. The present invention is applicable to a wireless charging system having different inductance, a low-inductance or low-voltage system works in a voltage doubling rectifier mode, and a high-inductance or high-voltage system works in a full-bridge rectifier mode. Moreover, a working mode of a rectifier can be automatically adjusted according to a voltage of the rectifier.
