well, I'm not suggesting it for an EV since it is deadweight (and you'd need a large cooling plate), but theoretically
12 of these should get you 300kw, and might have stationary uses as well.
And I wouldn't be surprised if a couple fell in someones toolbox while @ u-pull-it... But nobody seems terribly fond of the idea
mmm... 12 interleaved boosters... mmm...
edit: heck, you might be able to get rid of the capacitor if 6 converters are dumping current at any given time. though 12 high side gate drivers for regen is a bit much.
