Abstract

PURPOSE:To perform the reduction in the weight, loss and noise of a transformer by suitably determining the magnetic reluctance of a magnetic circuit, thereby approximately equalizing the magnetic flux density in the core in a laminar direction. CONSTITUTION:Iron plates forming legs 1 and both outside parts 7A, 7B of a yoke 2 in laminar direction, and iron plates forming the inside parts 6A, 6B are formed with equal thickness and different materials. Thus, the magnetic reluctances of the short and long magnetic circuits respectively passing through the outside parts 7A, 7B and the inside parts 6A, 6B of the core of D-shaped structure are approximately equalized.
