It's time for some parts ordering now....

if you need parts for the igbt driver boards, the only place i was able to find the high-voltage ultrafast diodes was ON semiconductor. i should have six extra coming.....the board requires 4 and i ordered ten. (free sample, so limited to ten, but they charge you 11 dollars shipping and handling.) i could send you half of them in an envolope when they get here if you want them.

I didn't see it over at the wiki. Can someone point me in the right direction?

Sweet! Thanks

Paul,

On the BOM for your 1000 amp controller you have listed the IRFP4668PbF as your power mosfets. I have some IXFK230N20T mosfets from a previous project. The ones that I have are the TO-264 case. Do you think they would work?

Thanks....
Rick

I have one problem. What voltage caps do I need to get? I feel like such a dunderhead.

Just finished my controller! Thanks to all who have posted to this forum and willing to share all of your knowledge. Special thanks to Paul for his help. Since I do not have enough posts to add the link to my video (I'm one away) I will be right back...

I must admit the evening started out pretty disappointing when I connected the battery cables and saw smoke coming from them. My first indication that something was wrong came when the light I was using for a pre-charge resistor did not go out. Having never done this before I thought maybe I falsely expected it to go out and connected the battery cables. That's when the smoke appeared. Luckily from the cables and not from the controller. Those with a keen eye will be able to tell what I did (Do not be thrown by the color of the battery clamps connected to the controller.)

I was tempted not to post this, but hope others may learn from my mistake. I will wait and see who can tell the world my error. If no one gets it (but I'm sure you will) I will describe the error of my ways.

i'm confused...i don't see any smoke anywhere.

I did not see any smoke . But the polarity of the bus bars looks like they are marked reversed.
