Amorphous Core for Power Transformers and Inductors

What Is an Amorphous Core for Power Transformers and Inductors?

An amorphous core is a non-crystalline magnetic material that offers several advantages over traditional silicon steel cores, including lower core losses, higher permeability, and better performance at higher frequencies. These cores are used in a wide range of applications such as power transformers, power factor correction inductors, energy storage filters, and medium-frequency transformers. The amorphous material enables improved energy efficiency, compact designs, and better performance in power electronic devices.

The amorphous cores are particularly effective in applications where low loss and high efficiency are essential, such as:

• Power Transformers
  For various power ratings and forms, ensuring low losses and high efficiency in distribution systems.

• Power Factor Correction (PFC) Inductors
  Enhance the efficiency of PFC circuits by maintaining low core losses at high frequencies.

• High-Power Transformers and Reactors
  Improve performance in large power transformers, high-power inductors, and reactors for industrial and commercial systems.

Key Features        

• Low Core Loss
  The amorphous cores provide significantly lower core losses compared to traditional silicon steel cores, which improves energy efficiency and reduces heat generation, even at high frequencies.

• Wide Frequency Range
  These cores are highly effective in applications operating from 50Hz to 10kHz, with capabilities extending up to 50kHz for high-power switch-mode power supplies and other high-frequency applications.

• High Permeability
  The amorphous material offers high initial permeability (~5000), enabling compact designs with fewer turns, leading to smaller and lighter transformer and inductor components.

• Excellent Thermal Stability
  These cores can operate effectively in a temperature range from –50°C to +120°C, making them suitable for use in a wide range of environmental conditions.

• Superior Frequency Characteristics
  The amorphous cores offer excellent performance over a broad frequency spectrum, making them ideal for high-efficiency power factor correction, energy storage, and EMI suppression.
