A transformer composed of corresponding sets of coils. Each group of coils basically consists of T1+K1+A1. Some are consists of T1+K1. There are also many forms of coil composition.

This article mainly describes the relevant functions and definitions of each magnetic ring in the T1+K1+A1 coil composition. Next we will introduce them one by one.

Network transformer

1. Network transformer T1
The transformer part of the network transformer. An electronic component that uses the principle of electromagnetic induction to transfer electrical energy or signals from one circuit to another.
Transformers are important components for the transmission of electrical energy or signal transmission.
Definition: Transformer, a combination of two or more stationary coils coupled with mutual inductance. What are the common uses of transformers? A transformer connects one coil to alternating power and connects the other coil to a load.
The alternating magnetic field transfers energy to the load and outputs power. The circuits that connect to the power supply are the original circuit (primary side) and the secondary circuit (secondary side). The voltages (effective values) of the primary and secondary coils are generally different, which is why the transformer gets its name.
We can divide transformers into two categories: iron core transformers and air core transformers. We wind the primary and secondary coils around an iron core (soft magnetic material) to make the core transformer. Utilize the high U-value of the core to enhance mutual inductance coupling. Widely used in power transmission and distribution, electrical measurement, welding and electronic circuits.

2. Network transformer T2
The common mode part of the network transformer is CMC, COMMON MODE CHOKE. The common mode choke resists useless and interference signals, as its name implies.
It forms a high impedance to common-mode noise signals and has basically no effect on differential-mode signals (useful signals).
It is the main component to resist EMI electromagnetic interference. Its working principle is as follows:
A common mode signal refers to a signal with the same polarity input at both input terminals. Common mode signals will cause electromagnetic interference. We divide electromagnetic interference into radiated interference and conducted interference (which enters the power line).
Asymmetric signal transmission and differential-mode signal conversion during impedance mismatch will produce common-mode signals in digital terminal equipment. CMC has no effect on differential mode signals. Differential mode signals refer to signals of equal size and opposite polarity input at the two input terminals. It does not produce radiation.

3. Network transformer T3
The Center tapped auto-transformer is another name for the auto-coupling part of the network transformer. The self-coupling transformer creates a high impedance to common-mode signals. It has basically no impact on differential mode signals.
Connect to the line according to the above wiring method. Efficient signal transmission can occur. This further reduces and resists common-mode electromagnetic interference.

The above is our introduction to each magnetic ring of the network transformer. I hope that through reading you will have a better understanding of the magnetic rings of network transformers.
