Simply elegant. Very KISS. I can do this. Is that a separate DC to DC converter in the last two pics? The 12v to 24v mentioned in the earlier posts?

Yes, but I just had a picture of a pretty big one. You can find them quite a bit smaller that have enough power to run it just fine. Mean Well has some 30w ones that would work fine that are almost half the size of the 50w one in the picture.

Very good. Thank you. Now to go shopping for some IGBT modules. What were those in the pics? 600w 400a?
I will have a 150ish volt power pack and a Warp 9 DC motor. Hopefully the power pack will get to 20kw, we shall see what the wallet and vehicle weight will bear...

The picture has 600v 600amp IGBTs. This type:
https://www.ebay.com/itm/3-Powerex-C...IAAOSwNchaMIwG
400amp ones would work fine too. The nice thing is, all 600v 50amp up to 1200v 600amp IGBTs have the same (almost) spacing for the 4 male 0.11" spade connectors across the bottom that plug into the control/driver board. Here's an example of some 600v 300 - 400amp IGBTs:
FF300R06KE3
Ebay also has some 400amp powerex/mitsubishi IGBTs. |

Yaaaa that is what I ment. 600 volt NOT watt. Monday fingers.
Three of 'em packaged and ready to go for half off! Wow. Wish I had the extra on PayPal. Would jump on that. Maybe there will be a deal on the 600v 400a ones soon.
Perhaps 400v 400a would work in my configuration? There seem to be lots of those available...

Let me know what you find ... as I will be shopping for some IGBTs myself in the near future ...

No problem. As soon six o'clock gets here, I am gonna be an Amazon shopper for IGBTs.
Thank you for all the lessons you have taught me here. You and Paul and a few others have really inspired me to get back into the truck upgrade. A few years ago one of the local EV clubs had a 'going out of business' sale where I picked up a slightly used Warp 9 and Ranger adapter plate for a song. They sat under the bench in the garage until I saw a comment somewhere about the open source controller. Being a Linux geek, I had to take a look. Am I glad I did. This is half the price of the commercial offerings, and looks to be twice as capable. Plus, it is repairable when I cook something in it. And programmable with serial interface. Awesome.

OK I found these. 400v and 400a for $133.00 each. They have a bunch of them. Looks like these are usable, except what are pins on the end for?
CHNsalescom Welder repair Infineon FF400R06KE3 400A 600V IGBT
600v 600a are either rare or horribly expensive. Perhaps in a few month Mouse will have them back in stock. |

They also have some similar to that on Mouser/Digikey. The 4 pins on the ends are the gate and emitter that plug into the control/driver board. then the board turns the IGBTs off and on.

Thanks Paul, I am going to go with these. 400v and 400a should be plenty to power the Warp 9 with a 120-150v 20kw battery bank. The batteries are going to be awhile before they get sorted out. I was lucky and resold the bunch of 10ah LiFEPO4 batteries I acquired. Heh for a profit to a local skateboard/bicycle shop that is starting to make and sell eboards and ebikes. They are doing very well here in the Cocoa and Cocoa Beach area of Florida.
Also the storm here in central Florida has just done some damage to roof. Leaking in the kitchen and bathroom. Gotta take care of that first...
