Introduction
Common mode chokes, also called electromagnetic interference (EMI) chokes, provide superior protection against electrical and audio-frequency interference. The B2005 application field and working principle of common mode chokes are based on the principle of magnetic field coupling between two electromagnetic flux fields, which results in the cancellation of the least desirable electromagnetic waves. This article will dive into the B2005 application field and working principle of common mode chokes, discussing what they are, how they work, and where they are used.
What is the B2005 application field and working principle of common mode chokes?
The B2005 application field and working principle of common mode chokes are based on the principle of magnetic field coupling between two opposite electromagnetic flux fields. This results in the decrease of unwanted and undesirable electromagnetic waves as well as the suppression of disturbances that frequently occur in electronic circuits. Common mode chokes are designed to reduce any form of electromagnetic interference and noise. The magnetic fields of the wire coils and the ferrite core act as a shield against the disruptive EMI and EMI emissions.
The B2005 application field and working principle of common mode chokes can be divided into two main categories. The first is the conventional choke structure which is made up of a single solenoid or a pair of coils wound in opposite direction on a ferrite core. The second is a two-wire choke structure with two coils wound in opposite directions on a ferrite core. The conventional choke structure is more effective at suppressing differential modeEMI, while the two-wire choke structuresuppresses both common mode and differential mode EMI, providing effective and reliable protection against electrical and audio-frequency interference.
The working principle of common mode chokes is based on a simple electromagnetics concept. The magnetic field coupling between two flux fields when induced voltages are equal and opposite produces a cancellation effect.
When an electrical current is applied to a common mode choke, it creates a magnetic field around the choke. This magnetic field interacts with the alternating electromagnetic fields from the EMI which cause interference signals in the receiving circuit. The interference signals created by the EMI are then suppressed and absorbed by the common mode choke due to the mutual interference of the EM fields.
Where is it used?
Common mode chokes are widely used in electronic equipment and devices to reduce electromagnetic interference. These devices play an important role in preventing disruptions in the data transmission caused by electrostatic and electromagnetic disturbances. Common mode chokes are commonly used in power supplies, cable systems, radio frequency devices, and communication systems.
Common mode chokes can also be used in telecommunications and aviation applications where directional antennas are used. These chokes are helpful in suppressing unwanted elements that can disrupt signals and cause problems in relaying information. Common mode chokes are also used in navigation systems, where the compass readings need to be accurate to ensure precise navigation.
Conclusion
Common mode chokes provide superior protection against electrical and audio-frequency interference. They are designed to reduce any form of electromagnetic interference and noise. The B2005 application field and working principle of common mode chokes are based on the principle of magnetic field coupling between two opposite electromagnetic flux fields, which results in the cancellation of the least desirable electromagnetic waves. Common mode chokes are widely used in electronic equipment and devices to reduce electromagnetic interference and are commonly used in power supplies, cable systems, radio frequency devices, and communication systems.
