Chengdu Mengsheng Electronics Co., Ltd, a leading manufacturer of power line filter products, provides comprehensive solutions for electromagnetic compatibility (EMC) and project implementation. With harmony becoming a mass issue, electromagnetic compatibility has become a crucial element, and choosing an appropriate AC line filter is an important aspect of it. The AC line filter acts as a bridge that filters out the unwanted harmonic frequencies from the network and regulates the voltage to make it usable for a Variable Frequency Drive (VFD).
VFD, which utilizes a rectifier to convert AC to DC, experiences harmonic distortion on the AC line due to nonlinear loads. This distortion can shift the power factor of the supply network and reduce the efficiency of the system. Harmonic distortion not only causes the electrical equipment to malfunction but can also result in downtime and damage to the equipment.
Mengsheng Electronics offers EMI filters, pulse group suppressors, and surge protection power line filters that are suitable for VFD applications. The filters can effectively reduce the EMI noise and suppress the pulse effects in DC and AC systems that derive from the nonlinearities in the VFDs. Furthermore, these filters prevent the VFDs from causing over-voltages or over-currents in other electrical equipment that are sharing the same supply.
To design an appropriate AC line filter for VFD, understanding the harmonics in the AC mains is essential. The filter circuit design involves calculating the required inductances and capacitances. With the help of the filters from Mengsheng Electronics, harmonic frequencies can be eliminated to less than 5% THD, thus ensuring compliance with standards such as EN55011, EN55014, IEC61000-3-2, and IEC61000-3-3.
The EMI filters from Mengsheng Electronics are compact and modular, making them ideal for VFD applications with limited space requirements. All the filters are designed to meet UL/CSA and TUV safety standards and are RoHS compliant. Customers can choose from a wide range of filter types, including single-phase designs with rated currents from 1A to 100A.
Since its establishment in 2006, Mengsheng Electronics has been committed to providing high-quality and technologically advanced power line filter products. The company continually invests in research and development and manufacturing to deliver innovative filtering solutions that meet the growing demand for electromagnetic compatibility.
