Alas, if automobiles used 48V instead of 12 ;-) They will. A few years ago 42 V (3x14 V) was supposed to be the new automobile voltage, but I have not heard much of it lately :-). I read about the engineering and design that was going into the "new 48V automotive systems" in the IEEE Spectrum in the last year or so. A brief Google search of ieee.org did not locate the article for me. Jonesy http://search.yahoo.com/search;_ylt=...earch&fr=b1ie7 |
