FIELD: physics.
SUBSTANCE: invention relates to method (6) for control of three-phase Vienna rectifier. Technical result is achieved due to that method (6) for control of three-phase Vienna rectifier includes several controlled power switches, each of which is connected to one electric phase. Method (6) also includes the following steps: conversion stage (60) of three specified linear voltages into three phase voltages; step of calculating (61) intended for unipolar component introduction depending on the sign of values of phase voltages and on average value of phase currents of three-phase Vienna rectifier; step of calculating values of "modulating signals" for each phase of a three-phase Vienna rectifier depending on the calculated input unipolar component and three phase voltages; and a step of generating (62) six switching signals of controlled power switches depending on the sign of the phase currents of the three-phase Vienna rectifier and on the calculated values of the modulating signals.
EFFECT: technical result of disclosed invention consists in simplification and increase in reliability of control of DC converter.
