Wow. I had no idea. Don't suppose you could run your brakes and steering from mechanical pumps coupled to your drive motor? That would be more efficient, and save you a bit of range. That's what I plan to do in the conversion I'm working on.
I agree with others that the parallel Vicor modules may be fighting with each other. Are they adjustable? If so, you could sum them via a Schottky isolator, but it will drop about 0.2 volt, which you'd probably want to adjust out. If you can't find Schottky isolators, you could sum the outputs via small resistors. 5 milliohms would drop only 0.2 volts at 40 amps, and would balance the load on the modules. Or you may want to can the parallel module concept, and use a single converter rated for the amperage you need. That's the most expensive option, but the other options all require more effort.

Even while the U.S. is at the epicenter of the food related public health crises, the U.S. government is trying to export its Food laws which deregulate the industry and over regulate ordinary citizens and small enterprise. This deregulation of the big and toxic and over regulation of the small and ecological is at the core of Food Fascism... -- Vandana Shiva :::: Jan Steinman, EcoReality Co-op :::: _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA)
