In an on-load tap changer (10) for controlling voltage of a tapped transformer (15) it is provided that

    the tapped transformer (15) has at least one regulatable phase (16) that has a first winding (20) and a second winding (30);the first winding (20) has a regulating winding (21) with even-numbered winding taps (23) and a main winding (22), and the second winding (30) has a regulating winding (31) with odd-numbered winding taps (33) and a main winding (32);the first winding (20) and the second winding (30) having the regulating windings (21, 31) of the even-numbered and of the odd-numbered winding taps (23, 33), are inductively coupled;the on-load tap changer (10) has a selector (40) for the alternating power-free preselection of the even-numbered or odd-numbered winding taps (23, 33) to be switched.
