Nanocrystalline C-Cores

New in VAC's product range are c-cores made of the nanocrystalline alloy VITROPERM with improved properties due to an optimized manufacturing process. Application areas are power transformers in converters or switched mode power supplies of higher power, welding converters or converters for inductive heating.

Advantages of nanocrystalline tape-wound cores are very low remagnetization losses, a high saturation induction as well as a low noise level during operation in the audible range due to the low magnetostriction.

The production of the new generation of nanocrystalline c-cores made of VITROPERM® is usually customized.
