Hi all, I need to know how to design high current boost DC-DC converters. For a regular DC-DC converter, I would usually use National's webench tool or similar to do the design for me, but how would I modify those to handle say 50 amps? I expect it's not just a matter of putting on a higher-current switch and passives rated for the higher currents, correct? Anyone have references/links to articles, books, tutorials, etc on this?
