Abstract

The embodiment of the invention relates to the technical field of PD modules, and discloses a PD module, which comprises a rectifying circuit used for obtaining an externally input direct current, a signature detection and power consumption grading circuit connected with the rectifying circuit, and a power converter; the common-mode resistance in the signature detection and power consumption grading circuit is 24.9 kilo-ohms, and the signature detection and power consumption grading circuit is used for indicating that the maximum power of the PD module is 12.95 W; and the power converter is connected with the signature detection and power consumption grading circuit and is used for converting the current output by the signature detection and power consumption grading circuit into required voltage and outputting the required voltage. According to the PD module and the power supply system, the ultra-small design of the PD module is realized.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of PD modules, and in particular to a PD module and a power supply system. Background technique [0002] Power Over Ethernet (POE) technology is a standard specification that can satisfy data and power transmission at the same time, and maintains compatibility with existing Ethernet systems and users, and is widely used in consumer and industrial products . [0003] A complete POE system consists of Power Sourcing Equipment (PSE) and Powered Device (PD), which often occupy a large space, hinder the structural design, and sometimes affect the installation of equipment. Therefore, there is an urgent need for ultra-miniature PD modules. Contents of the invention [0004] The object of the embodiments of the present invention is to provide a PD module and a power supply system, which realize the ultra-small design of the PD module. [0005] In order to solve the above technical pro...
