The invention relates to a phase shifting transformer (2) comprising: - 2 exciting windings (X1, X2, X3, Z1, Z2, Z3) sharing the same 3 double taped coils (4, 6, 8), - a first excited winding comprising 3 connected coils (41p, 42p, 43p), for a phase shift regulation, - a second excited winding comprising 3 connected coils (41v, 42v, 43v), for a voltage regulation; each of said 2 exciting windings regulating the voltage of one coil of said second excited winding (41p, 42 p, 43p), and regulating the voltage level of one coil of said first excited winding (41v, 42v, 43v). L'invention concerne un transformateur de déphasage (2) comprenant : - 2 enroulements d'excitation (X1, X2, X3, Z1, Z2, Z3) partageant les mêmes 3 bobines à double ruban (4, 6, 8), - un premier enroulement excité comprenant 3 bobines connectées (41p, 42p, 43p), pour une régulation de déphasage, - un second enroulement excité comprenant 3 bobines connectées (41v, 42v, 43v), pour une régulation de tension ; chacun desdits 2 enroulements d'excitation régulant la tension d'une bobine dudit second enroulement excité (41p, 42p, 43p), et régulant le niveau de tension d'une bobine dudit premier enroulement excité (41v, 42v, 43v).
