Nanocrystalline Power Transformer Cores
Nanocrystalline power transformer core is made by transverse magnetic-heat treatment to reduce core loss and residual magnetic induction, so as to obtain large working magnetic induction △B. This kind of core is suitable for push-pull type (full-bridge, half-bridge) converters.
High initial permeability: Larger insert loss, better inhibiting effect on conducted interference than ferrite.
High saturation induction: about 2-3 times higher than ferrite, hardly magnetized to saturate in the cases of current strong interference.
Excellent temperature stability: higher Curie temperature, the changes in alloy performance obviously lower than ferrite under the circumstance of larger temperature fluctuations, showing excellent temperature stability
Flexible frequency characteristic: More flexible to obtain the required frequency characteristic through adjustment process.
