Introduction

W6-00158 is a three-phase, high-frequency filter designed to reduce the common-mode (CM) or differential-mode (DM) noise generated in electrical power systems. This filter is particularly useful for the protection of power electronic components from noise disturbances and instability. It can be used in a wide variety of applications, such as variable frequency drives, motor controls, power supplies, systems for wind turbines and solar inverters, and more.

Application Field

W6-00158 filter can be used for applications in residential, commercial, and industrial installations. The filter is especially suitable for protecting inverters, variable frequency drives, and motor controllers from noise disturbances and instability due to its high-frequency performance. It is suitable for variable frequency drives that are operating in 30 kHz to 500 kHz, and can provide up to 75 dB of EMI reduction at 500 kHz bandwidth.Furthermore, W6-00158 filter can be used in industrial applications such as robotics, machine tools, and automated manufacturing systems. With its excellent characteristics, it is suitable for use in insulated-gate bipolar transistor (IGBT) drives, power supplies for industrial AC drive systems, regenerative braking systems, and frequency inverters to suppress any high-frequency noise and interference.

Working Principle

The working principle of the W6-00158 filter is based on the combination of two filter technologies: high-frequency inductors and capacitors. The high-frequency inductors are used to reduce the differential-mode noise, while the frequency capacitors are used to reduce the common-mode noise. The high-frequency inductors help to reduce the CM and DM noise by providing a low impedance path for the noise to travel through. The frequency capacitors help to reduce the differential-mode noise by providing high capacitive impedance which reduces the amplitude of the noise signal.The characteristics of the filter are adjustable, allowing for customised filtering to create a sharp rejection of a specific frequency band. In addition, the filter provides a low operational temperature rise and allows for a high filter efficiency (up to 80%). The filter is also designed to work in harsh environmental conditions, with an operating temperature range of -40°C (-40°F) ~ 125°C (257°F).

Conclusion

W6-00158 is an extremely effective and versatile filter designed for the protection of power electronic components from noise disturbances and instability. It can be used for a variety of applications, including residential, commercial, and industrial installations. Its combination of high-frequency inductors and capacitors provides excellent noise reduction and the adjustable characteristics mean a customised filtering solution can be created, depending on the specific needs of the application. Overall, the filter is suitable for use in harsh environmental conditions and has a high filter efficiency.
