Features:
Nanocrystalline cores for high frequency and high power transformers have high saturation flux density,
high permeability, low core loss, low saturation magnetostriction and good temperature stability.
Widely used as main transformer cores for uni-polar, push-pull or bi-polar type high frequency and high power switched mode power supply.
High saturation flux density and low core loss are the primary demand of a transformer,
and nanocrystalline core has the both properties. Transformers with nanocrystalline cores
have features of small size, high efficiency, low loss, low temperature rise and excellent temperature stability.
Applications:
> High frequency and high power switched mode power supply
> Laser power supply
> Inverter welding machine
> Electrical plating power supply
> Medium and high frequency heating power supply
> X-ray power supply
> IGBT Inverter
> Uninterruptable power supply (UPS)
Characteristics:
> High saturation flux density -- reducing volume of transformer
> High permeability and low coercivity -- improving efficiency and reducing magnetized current and reducing copper loss
> Low core loss -- increasing efficiency and reducing power consumption
> Excellent thermal stability -- continuous working at up to 120℃
> Low magnetostriction -- low audible noise compared to other materials
