Integrated fight through power

Since military vessels must fulfill mission requirements after sustaining baffle damage, survivability of the electric power distribution system is one of the primary attributes. The US Navy has been conducting studies to replace the basic architecture being used since the introduction of electricity aboard ships. The prevalent practice is to install a radial 450 VAC distribution system with mission critical loads supplied form two geographically separated power sources. Electro-mechanical bus transfer switches are provided to switch between the normal and alternate power sources. This paper describes the selection and benefits of the future shipboard power system architecture.
