す。The thin and compact transformer core of the present invention has the following features.
It can be made by forming a well-shaped groove in a square, round or polygonal core, and the thickness accuracy of the bottom surface, which is a problem when creating a thin core, can be made by cutting directly into the core. Because the accuracy can be greatly stabilized, the manufacturing process, characteristics, and design restrictions can be greatly improved.
