Abstract
dc:description.abstract<p>In this work a proof of concept for a step-down DC-DC converter used in a high voltage submarine application is presented. The purpose of the converter is to step down a 5000V-6000V input to a 24V output which can serve as an input to a submarine sensor. The completed system consists of two stages where the first stage is an unregulated switched capacitor converter to step down the initial input to a voltage range more appropriate for the selected second stage. The second stage is a regulated flyback converter topology which regulates the final output to the desired 24V. Performance evaluation of the proposed system are carried out using LTspice simulation software. Results of the simulation demonstrate that the proposed converter operates as anticipated with the first stage being able to reduce the initial input by a factor of 16 and the second stage producing a regulated 24V output. Additionally, the proposed converter reaches an efficiency of approximately 74.95% when tested under nominal input and full load conditions. With the same conditions, the converter yields an output voltage ripple of 1.525%, and line and load regulations of 0.0457% and 0.183% respectively.</p>
