Problems solved by technology

[0003] Ethernet is currently the most widely used LAN technology. With more and more Ethernet clients, the required power is increasing. However, most of the network transformers currently on the market can only meet the power transmission of about 36W. Obviously, this is far from meeting the needs of the current development, which makes the power transmission of network transformers seriously restrict the development of Ethernet

Abstract

The invention discloses a network transformer, in which four main magnetic coils of the network transformer are twisted with each other to form a four-core twisted wire, and the four-core twisted wire passes through the center of the main magnetic ring and is evenly wound around the main magnetic coil. The outer components of the ring. The secondary magnetic ring is arranged on one side of the main magnetic ring at a certain distance, and the first secondary winding and the second secondary winding are taken out of the four-core twisted wire of the main magnetic ring. The wires are twisted with each other to form a two-core twisted wire, which is evenly wound on the outside of the secondary magnetic ring to form a common mode choke coil. Each of the primary magnetic rings and each of the secondary magnetic rings form a winding, which suppresses common-mode signals, so that this technical solution realizes network transformer functions such as signal transmission, impedance matching, signal clutter suppression, and high-voltage isolation. .

Description

technical field [0001] The invention relates to the field of network transformers, in particular to a high-power network transformer. Background technique [0002] With the rapid development of electronic technology, network transformers used in networks have been widely used. In the environment of continuous innovation of electronic technology, domestic and foreign are committed to improving electronic products, making electronic products more miniaturized, planarized, functionalized and superior in performance. This requires network transformers to provide more reliable and better performance. Superior development. [0003] Ethernet is currently the most widely used LAN technology. With more and more Ethernet clients, the required power is increasing. However, most of the network transformers currently on the market can only meet the power transmission of about 36W. Obviously, this is far from meeting the needs of the current development, which makes the power transmissi...
