ELECTRICALLY-DRIVEN PLANT WITH CASCADE ELECTRIC CONVERTER Russian patent published in 2020 - IPC B60L50/13 H02M5/42 H02P27/06 B63H23/24 

FIELD: machine building.

SUBSTANCE: invention relates to the vehicles electrical traction systems. Electric make-up plant of vehicle with cascade electric converter includes control system, primary thermal engines with AC generators, automatic switches, electric converter and traction electric motor. Generator stator accommodates multi-phase windings isolated from each other, each of which is connected to its own automatic circuit breaker, and to the output of the electric converter there is a traction motor connected. Electric converter consists of single-phase frequency converters. At that, outputs of each automatic circuit breaker are connected to input of their single-phase frequency converter. Single-phase frequency converters are grouped by phases of electric converter and in each phase of electric converter are connected in series. Each of the single-phase converters in each phase is connected to different generators. Beginning of phases of the electric converter are connected to each other, and ends of phases of the electric converter are connected to phases of the traction motor.

EFFECT: technical result consists in improvement of performance of electromotive force system.
