Abstract (en)
An electric transformer (1) comprising left and right primary coils (20a, 20b), left and right secondary coils (22a, 22b) and a first magnetic circuit (10), the first magnetic circuit comprising left and right limbs (11a, 11b) connected together by upper and lower yokes (13, 14) so as to define an inner space (15), the left primary and secondary coils being wound around the left limb and the right primary and secondary coils being wound around the right limb, the electric transformer further comprising left and right bypass cores (31a, 31b) located inside the inner space of the first magnetic circuit, upper and lower ends of each of the left and right bypass cores being in contact with the upper and lower yokes of the first magnetic circuit, the left bypass cores being positioned radially from the left limb to be between the left primary coil and the left secondary coil and the right bypass cores being positioned radially from the right limb to be between the right primary coil and the right secondary coil.
