Summary

 
Object and purpose of research.This paper studies electric propulsion systems for various ships developed by SET Branch of Krylov State Research Centre over the years 2001–2018. The purpose of this study is to discuss technical requirements to marine electric propulsion systems, analyse design challenges caused by these requirements, as well as to suggest conceptual and design solutions intended to overcome these challenges.
Subject matter and methodsThe study is based on design documents (Technical Assignments, Explanatory Notes of different projects, principal layouts, outline drawings, etc.) issued under various development projects of marine electric propulsion systems, as well as on scientific & technical information available in theoretical literature about electric propulsion plants. Solutions to electric propulsion system design challenges described in this paper are based on the latest achievements of electrical science and technology (microchip-based control systems, static converters based on active rectifiers, multi-level voltage inverters based on the latest-generation semiconductor switches, as well as on the latest control algorithms for electric propulsion drives.
Main results.This paper briefly analyses current status of Krylov State Research Centre activities in development of various electric propulsion systems for ships. It discusses design challenges arising in this field due to the necessity to satisfy a whole number of tough requirements, often contradictory and sometimes exclusive. It describes conceptual and design solutions intended to overcome these challenges, as well as assesses capabilities and prospects of Krylov State Research Centre SET Branch in development of new-generation marine electric propulsion systems.
Conclusion.Practical results obtained by the authors confirm the role of Krylov State Research Centre as a valuable partner in development of electric propulsion systems for advanced ships, thanks to its qualified staff, many years of experience, as well as necessary manufacturing and test facilities
