Telecom 

 

From cell towers and network hubs to data servers and communication infrastructure, reliable power delivery is critical to maintaining uninterrupted service in the telecommunications industry.

Switch-mode power supplies (SMPS) are a cornerstone of telecom power systems due to their efficiency and compact design. These systems utilize inductors for energy storage and power conversion, particularly in non-isolated configurations where a single inductor serves as both an energy storage and a transformer replacement.

Key power applications in telecom include:

  • AC Input Filters: Filtering high-frequency noise from incoming AC power to deliver clean energy to downstream systems. A high permeability and low-loss material, such as nanocrystalline or ferrite provide superior EMI suppression.
  • Power Factor Correction (PFC) Inductors: Improving energy efficiency and reducing harmonic distortion in power supplies. Nanocrystalline, amorphous, and ferrite cores provide the best efficiency for high power PFC circuits, where powder cores can be used in mid-power.
  • DC-DC Converters: Regulating and transforming power to provide stable DC voltage for network equipment. Depending on the converter type, such as forward, push-pull, buck, or boost, and power needed, multiple Magnetics materials can be considered. 

As the telecom industry expands to support technologies like 5G and IoT, its power systems must evolve to meet demands for higher efficiency, more compact design, and reliability. Magnetics powder cores, ferrite cores, and tape wound cores are an integral part of meeting these demands and help drive connectivity forward.
