Common Mode Chokes

Common Mode Chokes are a type of electrical device used to reduce hazardous electromagnetic interference (EMI) in various electronic devices. Specifically, power supplies, motors, control systems, and communication lines, among others. The TTC-4090 application field and working principle are an example of this technology.

The TTC-4090 application field is predominantly when a single phase power supply of either a 115/230 V ac or a 48-110 V dc is used. It works in a variety of settings, including residential, commercial, industrial, and medical settings. Its range of applications includes medical devices, traffic safety systems, hi-fi audio systems, large-screen displays, gaming consoles, and more. One of the main benefits of the TTC-4090 is that components up to 1.5 kW are able to be connected to the product without the need for a separate transformer.

The TTC-4090\'s application field is further extended by its ability to reduce electromagnetic interference (EMI). It does this by reducing the common mode current, which is typically the most significant source of EMI in a system. This is achieved by creating a magnetic circuit, which restricts current flow from a single or multiple coils, reducing the amount of interference. As a result, it provides improved performance and protection of sensitive devices, as well as reduced radiation and noise. The TTC4090 can also be used in a variety of other applications, such as mitigating conducted emissions and conducting on/off testing.

The working principle of the TTC-4090 is two-fold. First, the magnetic core is placed inside the symmetrically structured coil. This coil is then "twisted" several times, resulting in the generation of a strong and uniform field. This field serves to restrict the flow of current along the central line. Secondly, the three windings of the coil are all oriented in the same direction. As a result, common mode current is reduced, which allows the device to better perform in EMI suppressed environments.

Conclusion

The TTC-4090 application field and working principle are an example of the advanced technology available to reduce hazardous electromagnetic interference (EMI). This type of technology is being used in a variety of fields, providing improved performance and protection of sensitive devices. The electrical device is also highly efficient, providing a magnetic circuit which restricts current flow and reducing common mode current. This article has outlined the application field and working principle of the TTC-4090, providing a better understanding of this type of technology and how it works.
