FIELD: electricity. ^ SUBSTANCE: device includes transformer (1), inductor (8), electronic switches of unidirectional conductance (11-22) and control unit of electronic switches. Transformer is made in the form of closed "¿"-shaped core with primary windings (2) and (3) located on its extreme rods, and secondary winding (6) located on its middle rod. Primary windings have middle outputs connected to each other for connection through resistor (9) to zero wire of three-phase AC network. One primary winding is intended for passage of positive AC half-periods along it, and its extreme outputs are connected to cathodes of switches (11-16) intended for connection of these extreme outputs through the above switches to phases of three-phase AC network. The other primary winding (3) is intended for passage of negative AC half-periods along it, and its extreme outputs are connected to anodes of switches (17-22) intended for connection of these extreme outputs through the above switches to phases of three-phase AC network. ^ EFFECT: increasing the uniform loading of phases and increasing the power. ^ 2 dwg |
