In the world of power line filter modules, 3VV1 is an industrial leader. It focuses on high-efficiency, long-lasting solutions for various applications and has become a popular choice across the board. In this article, we’ll be exploring the application fields and working principle of this remarkable device.

Application Fields

3VV1 is used primarily in medium to high voltage applications, such as mobile base stations, solar power systems, uninterruptible power supplies, automotive and industrial applications, healthcare equipment, elevators, and defense networks. Additionally, through its advanced design, 3VV1 can also be used for additional applications, such as equipment with accurate line frequencies, improved safety, and sharply reduced electromagnetic interference (EMI).

Working Principle

3VV1 is a single-phase three-wire common-mode filter composed of two parallel modules. Each module contains a capacitor, two inductors, and an impedance connection resistor in order to achieve common-mode impedance and differential-mode impedance. The capacitor blocks the DC component and the inductor can tolerate the frequency range in different applications. The impedance connecting resistor can effectively prevent electrical noise interference.

When the common-mode current passes through 3VV1, the common-mode voltage will decrease. Meanwhile, the differential-mode current will cause the differential-mode voltage to decrease. That is to say, when 3VV1 passes the electrical energy, the input/output impedance will decrease accordingly. Therefore, 3VV1 can effectively reduce the interference of common-mode noise and differential-mode noise.

Comparison with Other Modules

Compared to other power filter modules, 3VV1 has an advanced line noise suppression characteristics. The common-mode noise had a 19.1dB filter limit at 150KHz, while other filters such as L2N and LVL2 had only 6dB filter limit at 150KHz. 3VV1 also had higher tolerable voltage, a higher withstand voltage, and faster response than other modules. Its low power dissipation and faster recovery time, also allow 3VV1 to meet the needs of most industrial applications.

Conclusion

The 3VV1 power line filter module is an important device in industrial applications. Its advanced design and extended range of applications make it a great choice across the board. It has a wide frequency range and a higher tolerate voltage than other modules. With its high efficiency, long-lasting solutions, and low power dissipation, 3VV1 stands out as one of the leading power line filter modules.
