Common Mode Chokes (CMCs) are widely used for power-frequency applications, attenuating conducted currents from the power system to the connected equipment. CMCs also reduce the transmitted noise over a specific frequency range and contribute to the improvement of power systems’ electromagnetic compatibility. The CMCs may have a variety of different configurations depending on the application field and working principle.

In this article, we will present the application field and working principle of a type of CMCs called TCK-128. In general, TCK-128 is a kind of cryogenic common mode choke; it is specifically designed for use in extra-high voltage power systems. In addition to its capability to reduce common and differential mode noise, it is also able to deliver effective damping of resonances in both low and high frequency ranges.

The application fields of the TCK-128 include: High-voltage electric motors, Wind Turbines; High Voltage Switchgear; Capacitor Banks, CTs/ VTs; Lightning Arresters; Isolation Transformers; Uninterruptible Power Supplies; Aircraft Power Systems; Power Supplies; and Electric Trains. The main features of the TCK-128 are its high-performance attenuation of common and differential mode currents, and noise levels, enhanced by its cryogenic properties.

TCK-128s are designed with a flexible yet effective system call Shielding Core Technology (SCT). This system isolates the noise from one wire to another by using a high-permeability core, instead of a resistance absorbing the electromagnetic waves. With their SCT design, TCK-128s can reduce common and differential mode currents up to 35 dB depending on the frequency of the noise. Moreover, the choice of SCT ensures a low inductance for high-frequency applications.

In addition, the TCK-128 boasts a superior thermal design, making them ideal for cryogenic applications, as well as temperature-controlled ones. The superb thermal management allows a high current withstanding of up to 700 amps at a temperature of -60 °C. Moreover, the thermal design of the TCK-128 ensures an extremely low temperature rise, even when subjected to extreme power dissipation.

The working principle of TCK-128 is based on the Faraday law of induction. This law states that when a varying magnetic field is present, a current will be generated within a conductor. The principle of the TCK-128 is to use the Faraday law of induction to create a varying magnetic field, which produces a current in the conductor. As the current passes through the choked core of the CMC, it creates a resistance and hence, attenuates common mode and differential mode currents.

In conclusion, the TCK-128 CMC is an important device for power-frequency applications, capable of providing high-performance attenuation of common and differential mode currents, and noise levels. The excellent design of this CMC makes it suitable for wide range of applications, and its superior thermal design makes it ideal for cryogenic and temperature-controlled applications. The working principle of the TCK-128 is based on the Faraday law of induction, making it a reliable and efficient device for power noise attenuation.
