Characteristics of common mode filters, structure of common mode filters

Depus Electric will answer for you: 1. Filter out current harmonics, which can efficiently filter out the harmonics of 2 25 times in the load current, so as to make the distribution network clean and efficient, and meet the requirements of the national standard for distribution network harmonics. The product truly achieves adaptive tracking compensation, which can automatically identify the overall change of load and the change of load harmonic content and quickly track the compensation, 80us response to load change, 20ms to achieve complete tracking compensation.

2. Improve the system imbalance, which can completely eliminate the system imbalance caused by harmonics, and in the case of equipment capacity, the negative sequence and zero sequence unbalance components of the system can be compensated according to the user's settings and the reactive power can be appropriately compensated. On the basis of ensuring the function of filtering out harmonics, the system imbalance is effectively improved. 3. Suppress the resonance of the power grid, and will not resonate with the power grid, and in its capacity

Ferrite core, double wire winding. Low differential mode noise signals suppress interference sources and are difficult to deform in high-speed signals. Noise suppression countermeasures are excellent, high common-mode noise suppression and low differential-mode noise signal suppression.

Common mode filters are relatively simple in design and include common mode capacitors, baluns, or common mode inductors. A common-mode capacitor bypasses the common-mode current of the two input lines to ground, and the common-mode inductor exhibits a balanced impedance, that is, the impedance in the power line and the ground wire is equal, and this impedance exhibits impedance characteristics to the common-mode noise.

Summary. A common-mode filter typically consists of two high-impedance differential-mode input amplifiers and a low-impedance output amplifier. Between the two high-impedance inputs, a set of capacitors and resistors are connected in series to form a common-mode circuit.

The circuit filters out common-mode interference signals from the input signal and transmits only the differential-mode signal to the next circuit. Common-mode filters also typically contain an inductive element whose purpose is to filter out common-mode interfering signals in the high-frequency range. The specific type and number of inductive components depends on the design parameters of the filter and the desired filtering characteristics.

The structure of the common-mode filter is relatively simple, but it can effectively improve the anti-interference ability and signal quality of the circuit.

A common-mode inductor has a total of four pins. It is also common mode inductors in the field that are often used to play the role of filtering, suppressing common mode currents, and external silver radiation interference with other electronic devices, so as to effectively reduce the EMI problem.

When the working current flows through the two grips of the stool and winds around the opposite line of the stool, two magnetic fields that cancel each other are generated, and the working current is affected by the damping of the ohmic resistance of the coil and the leakage inductance, if the interference signal flows through the coil, the coil will show high impedance, which produces a strong damping effect and achieves the effect of attenuating the interference signal.
