I don't know how to post a link to a Youtube video without embedding it, and I'm not sure it's on topic; but some might be interested in seeing the innards of a Tesla power inverter.

EVTV Friday Show - April 28, 2017. Tesla Drive Unit - Inside the Inverter

Colin Kidder does the teardown from 1:41:48 to 2:02:18.

At 1:32:48 they show a Tesla drivetrain in a Lotus Evora putting 460hp into a $75K dynamometer. Must be nice.

Here it is. It was exciting to watch.

Do you really get away with that few capacitors on three phase motor controller? Seems they are using TO-247 IGBTs. I saw 7 IGBTs but there must be 7 more hidden there. At 1000 amps it would be over 70 amps per IGBT.

Now to see how much those IGBTs are I haven't even gotten into populating the control board yet but would like to end up with a 500A controller that eats 200VDC.

Getting closer to starting my converted IMA + Paul's controller board. Have my O-scope and signal generator at my house in CR. Have a crate on the way with the e-assist alternator and Honda IMA inverter along with a lot of other goodies inside.

Now, is there anyone that can verify a complete and UP TO DATE parts list to populate Paul's circuit board, and, is there anyone that can provide the programmed chip? I might be able to build the board up, but, have no desire to try the coding right now. There is so much info on this thread that I am not certain what is really up to date and where to source the required components.

I kept hoping someone would do a kit form of this board with all components, etc. Looks like a long journey for a non electronics experienced person to attempt, but, severely limited funds forces this endeavour to be pursued.

I'm hoping for lots of help-input to make this project workable. Everything will be posted on my controller mods thread in this fossil fuel free forum.

I started following this thread specifically because I like the logo and I want to put it in the back window of my car:



However, I notice the Wiki hasn't been updated

Could some authori-tay figure help with that?

I would just like to say that I have no idea how to edit the wiki. But this is the latest AC code:
hub.com/MPaulHolmes/AC-Controller
And you can email me at pandspowerelectronics@gmail.com to get all the files I have. I'm just busy right now with 2 separate jobs. My wife's copaxone is $2250/month starting in a couple months (after the insurance pays $9200, that's our "copay" lol), so we are saving up just in case we can't get extra financial help from the copaxone company. More fun than a barrel of monkeys! haha.

I tried to extract the relevant information from the Toyota MGR thread using the Mac OSX Summarize Text service; but I only got six pages in.

There must be a way to query the vBulletin back end and get a thread as a single block without the metadata; I haven't made much headway in Forum News & Feedback.

Summarize Text would ingest that in one gulp.

I have an older generation (no surface mount) controller. Since it's been a while since I've had a chance to play, I tried to update the flash with newer code located here:

https://github.com/MPaulHolmes/AC-Controller/branches

Seems like some of the pins have been changed and added. I'm planning to buy a new version board eventually but would like to get the latest version for this board.

Do you guys know where I can get this?

What version do you have? Actually, I'm not sure which version I have either ... so do you have a picture of the board?

I have several firmware upgrades that I loaded as my testing uncovered bugs and Paul released some new features, like save and putting the tests into the same firmware as the running controller code.

I have a few of the source files matched with the firmware.

i think I have serial number 2, so it may be too old to be of use to you. But we can try!

At one point it was running really well. But since I tried to get the regen working with the newer FW, it hasn't behaved since.

Thanks,
