The goal of the US Navy's Integrated Power System (IPS) program is to develop a power system architecture that will provide comparable performance of today's mechanically driven ships as well as reduce the owner's life cycle cost. In order to achieve this goal, the US Navy has been conducting technology demonstration of the Integrated Fight Through Power (IFTP). The IFTP is aimed to accelerate an interest towards the development of high power/low cost semiconductor switching devices. Cost reduction goal of the IPS is realized through the use of an open architecture for the power train as well as its control system. The architecture defines the partitioning of the module boundaries based on functionality and pre specified interface standards. The result is commonality across applications, standardization without inhibition, minimum number of equipment, non-vendor specific modules, minimum non-recurring cost for upgrades and dual use technology supported by both military and commercial devices and components. To enhance the survivability aspect, the US Navy is planning to replace the traditional power system architecture being used since the introduction of electricity aboard ships. This paper describes the selection and benefits of the Integrated Fight Through Power (IFTP), the future power system architecture, which will replace the traditional architecture.
