FIELD: electricity.
SUBSTANCE: invention is related to electric engineering. For this purpose device comprises power unit, unit of compensation, control system and voltage sensor. Power unit consists of serially connected converter transformer, commutation sensor, thyristor bridge and motor. Unit of compensation comprises serially connected device for calculation of alternating voltage component, comparison element, delta-modulator, commutation device, inverter and source of compensation current. Primary winding of voltage sensor is connected between circuit and "earth".
EFFECT: improved coefficient of voltage curve harmonicity distortion in current collector of electric locomotive.
