Power Electronics Technology Applications for Future SSBNs (By Using Switching Regulator Power Supplies in SSBN Electronic Systems, Reduced Costs and Improved Performance can be Reflected in Both the Electronic and Electrical Power Systems).

摘要

Conversion and use of electrical energy by electronic systems in present SSBNs are briefly described, along with problem areas in the present SSBN approach. As an alternative, a candidate electrical power system is proposed that is based on distributing either 160 or 270 V dc to electronic systems that use switching regulator power supplies for internal power conversion. The proposed technology has a potentially high leverage for achieving the SSBN goals of lower life-cycle costs, improved performance, smaller size, and less weight. Potential advantages over the present approach also include lower initial cost, more efficient cooling, lower power consumption, higher reliability, and superior performance. The several power electronic technological advances that are central to this approach could be beneficial to future SSBNs whether or not the alternative system, comprised of a dc source and switching regulator, is selected.
