Abstract

A transformer core made of magnetic strips is presented for use in a power distribution transformer. The transformer core has a desired height and a substantially cylindrical toroidal shape produced by winding a multi-layer structure about a central axis of the toroid in a spiral like manner. Each layer in the structure is composed of a predetermined number of magnetic strips arranged along the central axis with air gaps naturally existing between each two adjacent strips of the layer. A number <i>n</i> of layers in the structure is defined by the magnetic properties of the strips. The layers are shifted with respect to each other a predetermined distance along the central axis such that each of the air gaps in one layer is overlapped by (n-1) strips of the other layers of the structure.
