After a systematic review of topologies for the creation of a low voltage-high current DC-DC converters, an architecture was identified as having potential for addressing the growing power requirements of advanced electronic circuits and systems for use in space applications. The LLC with flyback converter was chosen because it provides compact and low mass potential with high performance against the system specification requirements. This choice was made after extensive numerical simulations of the structure, layout and system level performance. A working prototype of this system has now been fabricated and while there is still work to do, there are very encouraging results from the preliminary analysis. These results are presented in this paper with an explanation of the next steps to be adopted.

摘要

After a systematic review of topologies for the creation of a low voltage-high current DC-DC converters, an architecture was identified as having potential for addressing the growing power requirements of advanced electronic circuits and systems for use in space applications. The LLC with flyback converter was chosen because it provides compact and low mass potential with high performance against the system specification requirements. This choice was made after extensive numerical simulations of the structure, layout and system level performance. A working prototype of this system has now been fabricated and while there is still work to do, there are very encouraging results from the preliminary analysis. These results are presented in this paper with an explanation of the next steps to be adopted.
