FIELD: transportation; electricity.
SUBSTANCE: device contains carcass with detachable front and back shields, left and right side walls with sockets for connection of inlet control circuits. Along air flow direction, groups of power semi-conductor thyristor modular units are installed, assembled into six three-phase bridges with creation of six channels for electric energy conversion, which are connected to internal buses of three-phase AC and buses of every channel rectified current. Units for control of voltage supply to thyristor modular units of six conversion channels are connected to elements of current protection in every channel. Converter is equipped with chamber for location of mentioned control units and second electric insulating chamber for location of power thyristor units.
EFFECT: higher efficiency of device units cooling and higher reliability of operation.
