Abstract

The variable-ratio transformer includes a magnetic core made up of a main part composed of two yokes and legs in accordance with the number of phases and an additional part disposed on the side of the yoke of the main part of the magnetic core. The additional part of the magnetic core is made up of a yoke and legs whose number is equal to the number of the legs of the main part, at least one leg being placed with a gap in relation to the first yoke of the main part. - The primary winding of each phase comprises two series-connected parts, the first part being located on the main part of the magnetic core, while the second part is located on the additional part. A controlled electronic switch which regulates the load current flowing through the secondary winding of each phase, disposed on the main part of the magnetic core, is connected in parallel to one of the parts of the primary winding of each phase.
