APPLICATIONS
- Common made chokes used in EMC/EMI Filter far SMPS and inverter drives
- Transformer Cores for high frequency Switched mode power supplies
- Electrical welding power sources
- X- ray generators
- Battery charger
- Solar generators
- Sensor cores
- AC-to-DC & DC-to-DC converters
- Cores Used in Power supplies in the automotive industry
- Cores for saturable reactors, magnetic amplifiers, beads, and pulse compressors
- Railways Transportation Systems
- Electronic Watt-Hour Meters
- Transformer Cores for Earth Leakage circuit breakers (ground fault interrupters).
BENEFITS
- Significantly smaller build volume (up to more than a factor of 3)
- Satisfy both high saturation magnetic flu density and high permeability long with low coertivity.
- Makes the single stage filter designs possible.
- Low core loss (approximately 1/5th of the Fe based amorphous metal).
- Low magnetostriction, thus less affected by mechanical stress.
- Low number of turns required for high L, thus reducing number of filter stages.
- High ffcency hence low power loss and hence less use of material makesit eco friendly
- Very low audible Noise emission.
- Less copper loss due to reduced number of turns.
- Aging effects are very small unlike Co-based amorphous metals.
- Epoxy coated fiber glass tape/casing is resistant against mechanical stress.
- Excellent high frequency characterises as the value of permeabilities and core losses remain high and low respectively at very wide range of frequencies.
- Extended temperature range from -25°C…..+ 120°C (Standard) / 180°C (Special) due to high Curie temperature, thus making material properties nearly independent of temperature.
