Title:
DRIVER CIRCUIT OF VALLEY-FILL CIRCUIT, POWER SUPPLY MODULE AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/231633
Kind Code:
A1
Abstract:
Embodiments of the present application disclose a driver circuit of a valley-fill circuit, a power supply module and an electronic device. An input voltage end of the driver circuit is used for receiving a power supply provided by a primary winding or auxiliary winding of a direct-current conversion circuit, and a reference voltage end of the driver circuit is used for connecting to a power supply of an output end of the full-bridge rectifier circuit. The potential of the power supply provided by the primary winding or auxiliary winding of the direct-current conversion circuit is greater than the potential of the output end of the full-bridge rectifier circuit. The driver circuit may operate normally when the power supply module has a light load, thereby improving the stability of the power supply module.
