Beschreibung
Zusammenfassung:	The invention belongs to electrical engineering and may be used in electrical drives. The aim of the invention is the improvement of output voltage stability. There is suggested a method of electromagnetic phase number conversion, providing electromagnetic summation of increased frequency voltage amplitude, characterized by providing the number of half-periods of prescribed polarity of the A phase connected rectifier, repeating the number of half-periods of the same polarity produced by the B and C phases voltage, and continuous electromagnetic summing of half-periods of all rectifiers.Fig.2 provides the structure diagram of the method realization.
