HIGH-SPEED ENERGY-EFFICIENT ECOLOGICALLY CLEAN AND SAFE FOR PEOPLE ELECTRIC TRAIN Russian patent published in 2016 - IPC B61C3/02 B60L9/28 H02K17/28 

FIELD: transportation.

SUBSTANCE: invention relates to electric locomotives and motor cars. Electric train comprises head and trailer cars with 3-11 DC or AC traction motors of up to 500-1,800 kW supplied by catenary system. Every DC electric motor is connected with AC circuit through current collector, connected with transformer, with thyristor converters, with excitation winding, with solenoid and with storage batteries. Each traction AC electric motor is connected with the AC circuit via a current collector, is connected with transformer, with thyristor converters, with independent voltage inverter (IVI), with IVI control system and with control system of independent voltage rectifier (IVR). IVI supplies voltages to three stator windings of four-pole asynchronous electric motor, while the fourth stator winding is connected with a single-phase electrical network. Each electric motor stator windings are connected with separate 1-10 units of high-capacity capacitors.

EFFECT: higher energy saving and environmental compatibility of the vehicle are reached.
