Abstract
A phase converter for electrical signals is configured for obtaining a vector sum of phase signals or subdividing one signal into several phase signals, including transformers and configured for successive addition of signals received from secondary windings of the transformers and inversion of one or several of the signals, or for subdivision of the one signal into the several phase signals.

A phase converter for electrical signals, comprising means for obtaining a vector sum of phase signals or subdividing one signal into several phase signals, said means including transformers configured for successive addition of signals received from secondary windings of the transformers and inversion of one or several of the signals, or for subdivision of the one signal into the several phase signals, where in one or in several of the transformers a secondary winding is switched opposite to its prime winding forming an inverted signal, and in said one or several transformers in which the secondary winding is switched opposite to the prime winding forming the inverted signal the secondary winding and the primary winding have a common point connected to a nullifier or a grounding, while secondary windings of some of the transformers are connected in series.

A phase converter for electrical signals, comprising means for obtaining a vector sum of phase signals or subdividing one signal into several phase signals, said means including transformers configured for successive addition of signals received from secondary windings of the transformers and inversion of one or several of the signals, or for subdivision of the one signal into the several phase signals, where in one or in several of the transformers a secondary winding is switched opposite to its first winding forming an inverted signal, while secondary windings of some of the transformers are connected in series, further comprising an input, wherein a single signal which is vector V is supplied to the input of the converter, the single signal is divided into three signals including first, second and third, the first vector is obtained by turning a phase of the sector V by 60° by a capacitor or and inductance winding whose reactive resistance is greater than a reactive resistance of a load of the converter, the second vector is obtained by inverting a copy of the vector V, the third vector is obtained by a vector addition of copies of the first and second vectors.
