In order to reduce core loss in amorphous cut cores with air gaps. the effects of ferrite plates attached to cut surfaces of the cores were investigated. It was earned that the attachment of thin ferrite plates decreases core loss remarkably in amorphous cut cores with air gaps. It has also been discovered that this method of reducing core loss is effective in induction levels up to 0.7 T. Computer simulation of leakage flux in an amorphous cut core with air gaps suggests that this reduction is attributable to decrease of the leakage flux perpendicular to amorphous ribbon surfaces due to the attachment of the ferrite plates.
