CONVERSION COMPLEX OF DIESEL LOCOMOTIVE POWER SUPPLY Russian patent published in 2012 - IPC H02H7/00 B60L11/08 

FIELD: electricity.

SUBSTANCE: invention relates to power supply of vehicles, in particular, to power semiconductor converters for passenger and cargo diesel locomotives converting AC energy at the inlet into AC energy at the outlet. The conversion complex of diesel locomotive power supply comprises a three-phase traction synchronous generator, from the first to the fourth high-voltage converters, traction electric motors of the first and second trolley of a diesel locomotive, common manifold busbars of diesel locomotive power supply, auxiliary converters, besides, the first high-voltage converter is arranged from serially joined a three-phase rectifier and a multi-channel autonomous inverter of voltage for conversion of input AC voltage into output AC voltage controlled by amplitude and frequency, and the second high-voltage converter is arranged from serially joined a bridge voltage inverter, a matching transformer, a single-phase rectifier, the third high-voltage converter, arranged identically to the first high-voltage converter, and the fourth high-voltage converter is arranged identically to the second high-voltage converter.

EFFECT: exclusion of an auxiliary synchronous generator from diesel locomotive power supply, higher efficiency and reliability of a converting complex of diesel locomotive power supply due to usage of one source of supply, using auxiliary converters without rectifiers.
