Cool! Thanks for doing this and starting this thread.

My interests would be almost exactly what you've posted:

Battery voltage: 250V > 400V (based on Nissan Leaf battery packs)
Motor link voltage: 650V (based on Toyota hybrid motors)

For a charger, something that could deal with both 120AC minimum and 360DC from my solar system would be incredible!

If this could be pulled off in some svelt unit, or even combined with Paul's controller, that would be, um, orga....

For this to work out, I'm looking for power capabilities of about 50kW to 70kW. This would be only for boosting at high motor speeds, where a pack voltage of 400V would be inadequate. I don't have any interest in high speed charging, but the capability might be there anyway.

Oh, and running this at high switching speeds with SiC switches has my vote. Anything I can do to reduce weight is good. (by reducing inductor size) From my perspective, this part needs to be lighter than the batteries that could supply the difference between 650V and 350V, and put out a net 200kW. (multiple converters) So if the inductor is a huge, heavy part the net value may be negated.
