This document provides the technical background and bibliography for NELC TD 488, Reduction of Shipboard 400-Hz Power Requirements - Executive Overview, 1 October 1976. It points out the considerable costs and system penalties associated with shipboard frequency changers MG sets and explores technological methods of reducing the need for such equipment. It suggests that shipboard electrical equipments and systems be designed to use power in the form generated by the platforms primary electrical power source and that switching mode power supplies might be used as a method of eliminating the need for frequency changers. It explains that whether or not frequency changers are eliminated, the problems of reducing harmonic currents and powering pulse loads will remain. Recommendations include an educational program to make the problems and applicable new technologies known, modification of specifications and standards to require the use of power in the form generated by the platforms primary electrical power sources, and expansion of R and D activities associated with the remaining problems.
