INVESTIGATION OF CHARACTERISTICS IN THYRISTOR DRIVES WITH INCREASED POWER FACTOR IN CONDITIONS OF INTERMITTENT CURRENT

The original equations for calculating static characteristics of the electric drive in the intermittent current conditions have been obtained. The possible types of the boundary and intermttent current conditions have been classified. The semigraphical and computer methods for design of the static characteristics in electric drive have been developed. The device for change in turns of the converter control angles which improved its adjusting characteristics has been proposed.
