Problems solved by technology

[0004] However, multiple IP terminals can be connected to the POE switch through multiple IP ports of the POE switch at the same time. High power requirements; and after the EPS power supply is connected to the POE switch, only the EPS power supply supplies power to the IP terminal, and the power supply module of the POE switch cannot be effectively used

Abstract

The invention provides a power supply system. The power supply system comprises a power supply module and an extended power module; a rated output voltage of the power supply module is greater than the rated output voltage of the extended power module; the power supply module supports a constant-voltage power supply mode and a constant-power power supply mode; the power supply module is used for supplying power to a power receiving device accessing the power supply module; and the extended power module is used for supplying power to the power receiving device together with the power supply module, when the output voltage of the power supply module is the same as the rated output voltage of the extended power module. The power supply system provided by the invention can meet the power supply requirement of the power receiving device, effectively utilize the electric energy of the power supply module, and reduce the requirements on the output power of the power supply module and the extended power module.

Description

technical field [0001] The invention relates to the technical field of power supply, in particular to a power supply system. Background technique [0002] A POE switch is a device that transmits data signals for some IP terminals based on Ethernet, and can also provide power for these IP terminals. The internal power supply of the POE switch is limited. In order to meet the power supply requirements of the IP terminal, the POE switch usually needs to be connected to an external power supply to provide the required power to the IP terminal, such as an EPS power supply. [0003] In the prior art, after the EPS power supply is connected to the POE switch, the power supply inside the POE switch stops supplying power to the IP terminal, and all IP terminals connected to the POE switch are powered by the EPS power supply, that is, the IP terminal is only powered by the power supply module of the POE switch. powered or by the EPS power supply only. [0004] However, multiple IP t...
