IEEE 1709 DC Power Systems on Ships Working Group

For access to this group, please contact the Working Group Chair: Yuri Khersonsky

The IEEE DC Power Systems on Ships Working Group is sponsored by the Marine Industries Subcommittee of the Petroleum and Chemical Industries Committee of Industrial Applications Society and co-sponsored by the IAS Industrial Power Converters Committee and the Standards Committee of the Power Electronics Society.

The IEEE Std 1662-2008 "IEEE Recommended Practice for 1 kV to 35 kV Medium-Voltage DCPower Systems on Ships"has been published on November 2, 2010. The published standard is available from


This recommended practice addresses specific aspects of shipboard medium-voltage DC (MVDC) power systems and defines recommended practice for applying contemporary technologies to convert and distribute shipboard electrical power with improved reliability, survivability, and power quality. It is not intended in any way to impede development of new or improved techniques.

Target users for this recommended practice are evaluators and designers of electrical power systems for commercial marine and military applications, commercial and military ship end-users, shipbuilders, port operators, classification societies, machinery and equipment manufacturers, research institutes, and universities.


This recommended practice is based on current electrical engineering methods and practices for applying
1 kV to 35 kV MVDC power distribution and DC power delivery systems on ships. Recommendations are made for analytical methods, preferred interconnection interfaces and performance characteristics for reliable integration of MVDC electrical components into the ship electrical power systems.


The purpose of this document is to recommend methodology for analysis and specifications parameters for 1 kV to 35 kV MVDC power systems on ships. It describes impact of MVDC on all electrical components and formulates requirements on proper interfaces, sizing, life cycle cost, weight, efficiency and risk reduction of MVDC power systems implementation. It compliments the IEEE Std 45-2002 and IEEE Std 1662-2008.
