Product Description
This is a NAVAL POSTGRADUATE SCHOOL MONTEREY CA report procured by the Pentagon and made available for public release. It has been reproduced in the best form available to the Pentagon. It is not spiral-bound, but rather assembled with Velobinding in a soft, white linen cover. The Storming Media report number is A420173. The abstract provided by the Pentagon follows: As the Navy moves toward a modular DC Zonal Electrical Distribution System (DC ZEDS) to reduce both cost and weight over traditional radial shipboard distribution, there is a need to capitalize on technological advances currently available. The 21st century shipboard power distribution system calls for a DC bus architecture to eliminate the need for large transformers and thousands of pounds of cable through the use of high-speed semiconductor converters. In order to realize dramatic reductions in the size and cost of shipboard components through the use of high-speed switches, switch designs must be thoroughly investigated and tested. This thesis looks at the use of soft- switching techniques fOr use in the future DC-to-DC power converter modules of the DC ZEDS. Soft-switching is analyzed here primarily with a DC down/converter (buck chopper). A low voltage buck chopper is simulated utilizing PSPICE and modeled in the lab. A voltage feedback control algorithm is developed and utilized with the PSPICE model. A comparative study of circuit efficiency is done between a single-source and a two-source soft-switched topology. Finally, recommendations are made for further simulation and modeling to evaluate soft- switching, high-voltage performance capabilities.
