Applications:
The ferrosilicon magnetic core has distributed air gap, especially suitable for energy storage filter inductance in switching power supply because of its high BS value and low loss. It has a higher energy capacity compared with the iron core and ferrite with the same volume, permeab.
Therefore, it is widely used in rotary transformer, pulse transformer and power factor correction circuit because of its stable performance in high temperature. It can be smaller than the iron core, and now it is used to replace the iron core for the transformer. It can also be used for noise filter inductance without noise and magnetostriction
