Common Mode Chokes Common mode chokes are commonly used in various applications, including those in motor control, telecommunications, and audio systems. They are designed to reduce electromagnetic interference (EMI) and radio frequency interference (RFI) from being radiated or conducted within an electronic system. The most common application of common mode chokes is as a filter for noise in power supplies.Common mode chokes use transmission line theory to reduce common mode current flow at certain frequencies. They work by redirecting or suppressing the flow of these currents between two circuits. They do this by creating an impedance in the line to prevent common mode current from flowing freely between the two circuits. Common mode chokes are usually built using a combination of inductors and capacitors to achieve the desired impedance. The common mode choke is typically used in conjunction with a bypass capacitor placed on either side of the choke. The capacitor provides a low-impedance path for the common mode current to flow, while the choke provides a high-impedance path for the same current. This combination of the choke and the bypass capacitor works as a filter to reduce EMI and RFI from being radiated or conducted within the system. Common mode chokes are usually made from ferrite core material. Ferrite core material is a type of magnetic material that has high magnetic properties, which allows the flux to be more efficiently utilized. The core material also has low electrical properties, which allows the current to flow through the choke without being affected by the core material. Common mode chokes are available in a variety of shapes and sizes. The most common type of common mode choke is a U-shaped configuration, which is a two-coil configuration. This configuration provides the best suppression of EMI and RFI. Other common configurations include E-shaped, T-shaped, and S-shaped chokes.Common mode chokes are also available with various dielectric materials. These materials are used to reduce leakage currents between the coils. The most common dielectric materials used are PTFE, Kapton, and silicone. The type of material used depends on the application the choke will be used in and the amount of leakage current that is tolerated.Common mode chokes are also available with various inductance values. Common mode chokes are usually rated to have an inductance of between 500uH and 5,000uH. The inductance value of the choke determines the frequency range in which the choke will provide the best suppression of EMI and RFI. Common mode chokes are designed for AC applications. They are usually rated for a certain voltage, typically up to several hundred volts, and they can be used for currents of up to several hundred amperes. Common mode chokes can be used in single or multiple-phase applications. Common mode chokes are used in a variety of applications, including motor control, telecommunications, and audio systems. They are designed to reduce EMI and RFI from being radiated or conducted within an electronic system. The most common application of common mode chokes is as a filter for noise in power supplies. Common mode chokes are available in a variety of shapes, sizes, inductances, and dielectric materials.
