Explain the difference between common mode inductors and differential mode inductors in detail -

Common-mode inductors are introduced in detail. Common-mode inductors, also known as common-mode choke coils, are generally used to filter the magnetic effect interference signal of the common-mode current of computer toroidal transformers. In power supply design, common-mode inductors are also used as EMI filtering devices. Used to suppress ionizing radiation caused by pushing high-speed signals outward. 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. It is mainly analyzed by two aspects: the same specification and model data information, the same coil structure, and the number of turns of the coil. The symmetrical coil inductance is on the same ferrite core toroidal transformer frame, forming itself a four-terminal electronic device. It is necessary to show the existence of a large inductance digital model for the middle development trend of the common mode signal, and it will definitely be able to restrain social and economic development. The effect of influencing factors, but for the differential signal management information system, some small leakage inductances are mostly ineffective. When the basic concept is that the common-mode currents accumulate in mutual flux flow, it is beneficial to have a very large inductance to suppress the common-mode currents, and when the currents of the two audio signals passing through the coil, according to the magnetic ring Cancellation of interaction, basically no inductance, the differential current flow can exceed the transmission coefficient. Common mode inductance can effectively suppress the balanced development of common mode interference signals in the line, but it may not harm the audio signal transmission method signal of the normal driving route. Differential mode inductance is introduced in detail. Differential mode inductance is a characteristic of the closed-loop control system, that is, when the amount of current 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), which is their own closed-loop control system characteristic. Assuming that the company conducts analysis, a student can change the amount of current based on the closed loop. Due to the influence of the induction coil in China, the induced electromotive force is not closed. This kind of inductance is called mutual inductance. ). The inductor circuit element is implemented specifically with the inductance circuit. A solenoid is a simple inductor, which refers to a multiple-wound cable (called a 'coil'), which can be hollow inside or have a Chinese metal core. Magnetic effect of electric current Inductance self-inductance. .The transformer is the inductance caused by the middle of the coupling coil 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 wires of common-mode inductors are generally bidirectional; one-sided differential-mode inductors are rewinded. 2. The common mode damage suppression filter can be called according to the common mode in the inductor; the differential mode damage suppression filter, and the inductor called the differential mode inductor. 3. Equivalent to the same number of coil turns around the core, equal to the diameter of the power line, winding two opposite coils is a common mode inductor; differential mode inductors are coiled around the core of the coil. 4. Common mode signal: two different aspects of the main influencing factors in the learning process of the neutral line and the live line can be based on the same signal; differential mode signal: suitable for the same control circuit in the communication system. The characteristics of common mode inductors: 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 raw material of the high-conductivity ferrite core is the top raw material sold in the market. Differential mode inductance characteristics: In the case of high current applications, because it is not important for the agent in the coil winding, when the current flow across the coil expands to the coil of the transformer 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 cost-effective.
