FIELD: converter engineering.
SUBSTANCE: proposed voltage regulator designed for symmetrical mode of operation incorporates provision for simultaneous and similar voltage regulation in all three phases with aid of one switching member in the form of transistor switch at output of three-phase diode bridge connected through ac terminals to loose leads of primary windings, one switching member being used for the purpose in unipolar boost voltage circuits or two ones, in bipolar boost voltage circuits.
EFFECT: reduced number of transistor switches designed for periodic connection of primary windings to supply mains.
