Title:
POWER SUPPLY SYSTEM, VOLTAGE SETTING APPARATUS, VOLTAGE SETTING METHOD, AND COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/078028
Kind Code:
A1
Abstract:
A power supply system (100), comprising an input port (10), an output port (20), a first voltage converter (30), and a second voltage converter (40). The first voltage converter (30) is used for measuring an input voltage of an external input voltage source (50), adjusting the input voltage of the input voltage source (50) to be within a set voltage range when the input voltage of the input voltage source (50) is not within the set voltage range, outputting the input voltage to the second voltage converter (40), and directly transmits the input voltage of the input voltage source (50) to the second voltage converter (40) when the input voltage is within the set voltage range. The second voltage converter (40) receives an output voltage of the first voltage converter (30), adjusts the output voltage of the first voltage converter (30) according to a first set proportion, and outputs the output voltage to a load (60).
