Embodiment Construction

[0015] Such as figure 2 As shown, the Ethernet power supply test equipment of the present invention includes a data input and output interface, an isolation transformer, a polar rectification network, a current mode controller, a DC / DC optimized control isolation power conversion network, a load switching control network and an automatic load test network. The data input and output interface is connected with the isolation transformer. Isolation transformer, polar rectifier network, DC / DC optimized control isolation power conversion network, load switching control network and automatic load test network are connected in sequence. The polar rectifier network is further connected to the current mode controller. The data input and output interface is usually RJ45 interface.

[0016] The input and output interface receives the data and detection signals output by the Ethernet power supply device. The isolation transformer is used to isolate the power supply voltage and the data si...

Description

Technical field [0001] The present invention relates to the field of communication, and in particular to a power supply over Ethernet test equipment. Background technique [0002] With the rapid development of technology, devices based on Power over Ethernet (POE) technology have been widely used. Power over Ethernet is an innovative technology and is used more and more for network Power supplies for equipment, including IP phones, wireless LAN access points, web cameras, and other network applications. In the POE system, the equipment that provides power is called PSE (Power Sourcing Equipment), and the equipment that uses power is called PD (Power Device). The PSE is responsible for injecting power into the Ethernet cable and implementing power planning and management. But power-over-Ethernet test equipment has become a problem for many companies that produce power-over-Ethernet equipment. [0003] See figure 1 , PD devices currently on the market include network interfaces, i...
