Abstract
In the given work were made the comparison of new three-phase high-voltage rectifiers with the classical scheme of 12-pulse rectifier. It is shown, that in the new scheme of three-phase threezone (n-zone in generally) rectifier the number of thyristors essentially decreases and reverse voltage on gates decrease. The figures of factors of harmonics of output voltage, an input current, and also a power factor, received by computer modelling in PSIM are presented. In the conclusion all results have been taken to the total table.
