Detailed introduction of common mode inductor Common mode inductor is also called common mode choke coil, which is generally used to filter the magnetic effect interference signal of common mode current in computer toroidal transformer. In power supply design, common mode inductor is also used as EMI Filtering device for suppressing ionizing radiation caused by outwardly pushing high-velocity signals. The common mode inductance is a common mode hazard with the transformer skeleton as the ferrite core. We can analyze it based on the electronic components in our country, which are mainly analyzed by the data information of different specifications and models in two aspects. The coil structure and the number of turns of the coil are the same. The symmetrical coil inductance is on the same ferrite core toroidal transformer skeleton, creating itself a four-terminal electronic device. It is necessary to show the large inductance digital model for the development trend of the common mode signal. The existence of digital models can certainly inhibit social and economic development. Influencing factors, and for differential mode signal management information systems, which show some small leakage inductances, most of them do not work. When the basic concept is that the common mode current is accumulated in each other, it is beneficial to have a very large inductance, which prevents the common mode current. Undo each other, most of them have no inductance, and the amount of differential mode current can be overturned without transmission coefficient. The common mode inductance can effectively suppress the balanced development of the common mode interference signal in the line, but it may not harm the audio signal transmission data method signal of all normal driving routes. Differential mode inductance is introduced in detail Differential mode inductance is a characteristic of the closed-loop control system, that is, when the current amount changes according to the closed-loop control system, the induced electromotive force will appear to resist the change of the current amount. This is called self-inductance (self-inductance) and it is their own closed-loop control system characteristic. Assuming that the company conducts analysis, a student can be changed according to the amount of current in the closed loop. Due to the influence of the current induction coil in China, the induced electromotive force is not a closed loop in such a country. This type of inductance is called mutual inductance. ). Inductor circuit components and inductance circuits are specifically carried out. A solenoid is a simple inductor, which refers to a multiple-wound cable (called a 'coil') that can be hollow inside and can have a Chinese metal core. Magnetic effect of current inductance self-inductance. .The transformer is the inductance caused by the middle of the coupled coils of the two systems. A transformer is a basic equivalent circuit electronic device due to its mutual inductance.

The difference between common mode inductors and differential mode inductors

1. The winding wire of the common mode inductor is generally bidirectional; the single-sided differential mode inductor is wound by the wire winding machine.

2, the common mode damage suppression filter device can be called according to the common mode in the inductor; the differential mode damage suppression filter device, and the inductor called the differential mode inductor.

3. Equivalent to the same number of coil turns around the core, equivalent to the diameter of the power line, winding two opposite coils is a common mode inductance; a differential mode inductance is coiled around the core of the coil.

4. Common mode signal: The two different aspects that lead to important influencing factors in the learning process of the neutral line and the live line can be completely based on the same new number; Differential mode signal: suitable for the same control circuit in the communication system . The characteristics of common mode inductance: The transformer coil is not afraid of saturation, because the two sets of coils on the same transformer coil are wound in opposite directions. The high-conductivity ferrite core material is the top material on the market. Differential mode inductance characteristics: In the case of large current applications, because it is not important for the agent in the coil winding resistance, when the current volume expands across the coil to the transformer coil of the coil will be saturated, the core material is iron market sales The most important structural raw material in the world, because the market price is very reasonable.
