The electromagnetic thyristor converter of the numbers of phases and of frequency for a supply of the powerful single-phase electro-consumers

摘要

The connection of powerful single-phase loads to the supplying three-phase networks gives asymmetric conditions, which are characterized by the asymmetry of currents and, therefore, asymmetry of voltages. The symmetrizing of three-phase networks with the help of jet phase-shifting elements does not give the desirable results. The results of the research of the electro-thyristor converter of a three-phase system of voltages into the single-phase voltage without using of jet phase-shifting elements, are given in this report. The device, along with transformation of number of phases, ensures multiplication of frequency by 1.5 times with simultaneous symmetrizing of currents of a supplying three-phase network.
