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 with a cascade electric converter includes a control system, primary thermal engines with alternating current electric generators, automatic switches, an electric converter and a traction motor. To each multi-phase winding output of the generator its automatic circuit breaker is connected. Electric converter consists of single-phase frequency converters, and outputs of each automatic circuit breaker are connected to input of their single-phase converter. Single-phase converters are grouped by phases of electric converter and in each phase are connected in series. Phases of the electric converter are connected to each other, and the ends of the phases are connected to phases of the traction motor. Each of generators has electromagnetic excitation system consisting of excitation winding and additional electric converter of excitation winding. At that, electromotive plant comprises multiphase voltage sensors with information outputs of which are connected to control system.

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