Adam,
You already had my attention, now I am drooling. Gotta clean up my keyboard.
This is fabulous work. I take it you do this for a living when you aren't up to your elbows in grease.
The limitations that I saw in Paul's basic kit seem to be totally solved with your design/implementation. I was worried that I would need more amps with my application and it seems you have solved that in spades. Paul has been saying that his will support 500 amps with no problem and that is with 11 mosfets sharing the load. Can I safely assume that your design will handle more than 1000 amps? I know that the mosfets are designed with a limit of 200 volts and Paul mentioned that he thought that 144 volts was the max safe limit that should be followed. But then again you are looking at 161(?) volts. Is your confidence in that limit based on any other changes that you have made?
I am still in the design stage of what I want to do. And what you have here seems to fit quite nicely for me. Any chance that you are going to offer a kit or at least pcb's and bom to aid the ambitious folks lacking in EE skills like myself? I'm sure that I am not the only one thinking along these lines.
Nice work and I appreciate you sharing those purdy images.
Thanks again.
Eric
