ELECTROMOTIVE PROPULSION PLANT OF SHIP WITH SEVERAL PROPELLERS Russian patent published in 2020 - IPC B60L50/13 H02M5/42 H02P27/06 B63H23/24 

FIELD: electricity.

SUBSTANCE: invention relates to the vehicles electrical traction systems. Proposed device with several propellers comprises control system, generator set, automatic switches, voltage rectifiers, voltage inverters and traction motors mechanically connected with propeller. Circuit breakers, the number of which is equal to the number of isolated from each other electric windings of the generator unit and the number of voltage rectifiers, are connected by their output contacts to the input of voltage rectifiers. Number of voltage inverters of each electric converter of traction motors is equal to number of voltage rectifiers number of which is multiple of number of phases of traction motor. Single-phase voltage inverters of each of electric converters are grouped by phases of converter and in each phase inverters are connected in series. Beginning of the phases of the converter are connected to each other, and conditional ends of the phases of the converter are connected to phases of the traction motor. Each of inverters of each converter is connected by its input contacts to output of its voltage rectifier.

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