DC-DC Power Conversion With Galvanic Isolation

Abstract

As the navy transitions to all electric warships, there will be many changes to the power distribution schemes found aboard ships today. It will be necessary to maintain reliability while supplying the various components onboard with the proper voltage levels, Since transformers cannot be used to alter voltage levels while providing galvanic isolation in DC power systems, it is necessary to find an efficient method to incorporate the increased safety provided by galvanic isolation in a DC power distribution system. This thesis examines the design and control of one possible element for a future Electrical Distribution System (EDS), a DC-DC converter with galvanic isolation. The main purpose of this study is to provide a working model with associated theoretical proof and simulations. MATLAB will be used to provide observations of the converter's operation and the success of the control scheme implemented. Future work on this topic will be assisted by the inclusion of a parts list as well as recommendations for enhancing the prospects of this technology.
