Title:
POWER SUPPLY SYSTEM FOR REDUCING POWER CONSUMPTION AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/184363
Kind Code:
A1
Abstract:
A power supply system for reducing power consumption and an electronic device. The power supply system comprises: a restart circuit (1) and a controllable power supply circuit (2), wherein one end of the controllable power supply circuit (2) is connected to a power supply source, and the other end of the controllable power supply circuit (2) is connected to a system power supply port (3); a control end of the controllable power supply circuit (2) is connected to a microprocessor; the restart circuit (1) is connected to the system power supply port (3), and the system power supply port (3) is connected to the microprocessor; the controllable power supply circuit (2) is turned off or on under the control of the microprocessor so as to cut off or provide power to the system. The restart circuit (1) is used for restoring the power supply to the microprocessor by providing a power supply signal to the system power supply port after the system power supply is cut off, so that the microprocessor controls the controllable power supply circuit (2) to be turned on after the power supply is restored. The power supply system can effectively reduce the power consumption of the device and has a simple circuit, and conventional components are used to effectively save costs.
