You do realise cars run off dc!? A tranformer won't do anything without some sort of AC source.

what you need is some kind of DC/DC converter. That'll convert the 12v car battery supply to your 40v 15A.

I think what this person is saying is that he's designing the DC/DC converter himself.

He mentioned the mosfets that he's using, and just wants suggestions on making an appropriate transformer for it.
