FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering, in particular to the field of conversion equipment and automated electric drive. Technical result is achieved due to control of alternation of power circuit phases and control of coincidence of power circuit phases, as well as absence of false actuation of device due to voltage failures in control circuit with continuous control of phasing. Device for phasing control of three-phase electric drive includes three D-triggers, three zero-elements, three filters, three logic elements NAND, two logic elements AND, actuator.
EFFECT: improved functionality of the phasing control device.
