FIELD: transport.
SUBSTANCE: invention to electrified transport facility supplied by DC power sources. Converter input is connected to electrically driven vehicle DC main supply line. Note here that in vehicle inertial motion with main line disconnected from overhead system, proposed method comprises the following stages: motor magnetising, operating motor in variable voltage generator conditions, tripping converter with main line DC voltage reaching upper threshold limit, and maintaining converter as-tripped as long as main line constant voltage exceeds minimum constant voltage that excites induction motor.
EFFECT: reliable peak-traction and regenerative braking conditions, reduced power losses.
