FIELD: electricity.
SUBSTANCE: speed control device of electric stock contains two groups of DC railway motors, the armature windings and the exciting winding of which are connected in the cross-sectional scheme. The totally controllable thyristor (14) carries out the resistor shunting and controls the armatures current of direct current railway motors both groups in the mode of impulse regeneration. In the absence of the consumer, the recuperative rheostatic or rheostatic braking mode is realized by the combined operation of totally controlled thyristors (14) and (15).
EFFECT: energy efficiency of the recuperative-rheostat braking increase.
