I've currently got IRF Z44N parts that I'm testing.

A couple of images of what I'm thinking will be a better setup...

Questions? Comments?

Hi Mario,
While i don't mind helping in the testing phase, I am not much help in the design/building phase.

Connectors on top of board, switching devices on bottom. I don't think there is a problem with heat sinks on bottom since "on" time is short. Is there a schematic and/or specification?

Thank you / Robert

I’m working on a new schematic now. the Purpose of the daughter boards is to ease assembly and repair. It will also allow for different boards to be created without a full redesign so you could have one board that handles 3 standard pads and another board that has a single pad with fill and purge for hybrid systems. Other possibilities exist.

Moving the MOSFETs to the bottom gets them out of the way of the connectors. It will also create a bit of a tunnel effect around the components so, if needed, a fan can be added with a thermistor to actively cool them.

Do you live on the east side of Indy? Maybe we can get together and I can show you some of this stuff.

Near Kennard west of New Castle - W. Henry county. Not too far, I can do that. I also have some 12VDC 2" fans I scrounged if needed. Very low current - you could run these 100%.
