An adjustable transformer comprising a core with two yokes and limbs, primary and secondary power windings, one of which has a supplemental section of turns, at least one of the transformer yokes being made of at least two parallel-connected controlled magnetic circuits forming an additional transformer opening making room for housing the supplemental section turns of the power winding. Each parallel-connected magnetic circuit is provided with bias windings connected to the control network and ensuring a magnetic switching of the supplemental section of turns of the power winding. The switching is a movement of the supplemental section of turns in and out of the transformer open-circuit magnetic flux field.
