Metglas - Powerlite

High Frequency C-Cores Technical Bulletin            
                   
POWERLITE® C-Cores are manufactured with iron-based METGLAS® amorphous Alloy 2605SA1. Their unique combination of low loss and high saturation flux density take advanced power conditioning applications to higher performance levels than previously possible with conventional ferromagnetic materials.

Applications

For a wide range of high frequencies and hot-spot temperatures (up to Class F), POWERLITE® C-Cores are used in a growing list of advanced power conditioning applications including:

  • UPS and SMPS Power Factor Correction Chokes
  • UPS Harmonic Filter Inductors
  • High-Power Outdoor Industrial Ballasts
  • Welding Power Supplies
  • High-Speed Rail Power Systems

Benefits

Manufactured in a variety of ultra-efficient core configurations, POWERLITE® C-Cores provide significant cost, design and performance benefits over ordinary Si-Fe, ferrite and MPP cores such as:

  • High Saturation Flux Density (1.56 T)
  • Low Profile – enables weight and volume reductions of up to 50 %
  • Low Temperature Rise – enabling smaller compact designs
  • Low Loss – resulting from micro-thin METGLAS® ribbon (25 µm)
