摘要

A transformer core includes a plurality of first and second outer leg plates (106, 108), a plurality of inner leg plates (110), each having opposing, arc-shaped ends (122, 124), and a plurality of upper yoke plates and a plurality of lower yoke plates (102, 104). Each of the upper and lower yoke plates has an outer side and an inner side with an arc-shaped notch formed in the inner side (129, 130). The inner leg plates, the upper and lower yoke plates, and the first and second outer leg plates are joined to form first and second outer legs from the first and second outer leg plates, respectively; an upper yoke and a lower yoke from the upper and lower yoke plates, respectively; and a central leg from the inner leg plates, with each arc-shaped end of the inner leg plates being joined with an associated arc-shaped notch of each of the upper and lower yoke plates.
