IGBT driver board

[badfishracing]

Got it today.

Very nice piece of hardware. Can't wait to assemble.

Do you still boards available?

Yes, I still have a few but NOT parts kits.

Hi, can you send a paypal a paypal invoice for the driver board?, and if you have some of the parts you can add the additional cost?

Paypal invoice to: richardriver01 (at) aol.com

Thanks

just sent the paypal payment 2 boards populated + 2 vla500 igbt drivers.. (echeck will take 3 days to post)

Thanks Ric

Long distance Big thanks to Horacio (MrBigh)
IGBT boards arrived and I'm looking forward to the build!

I will add some PCB artwork files to the wiki soon.

We've got a thread going on the overall controller on DIYcar, but this is specific to the VLA driver board from this thread so I thought this would be a more appropriate place to ask.

We're getting a strange output from the VLA500 board.
At first we thought it was the IGBT, but it is not. (we have other problems with the IGBT: gate resistors etc to sort through).

The output from the P&S controller board shows a clean 8khz signal. The output from the VLA board has unstable transitions between the 8khz main pulses. They SEEM to be more prevalent when the duty cycle is ramping up and go away when it is stable.
Here are a couple of screenshots of the gate-emitter trace with the unwanted pulses. The controller board signal has clean pulses every 6.25 divisions (125 u-sec).


My son made some mods to disable the desat detection (shown) and pull the gate resistor off of the driver board.


Can you see any obvious places to start to look for the cause?

Thanks

I'm looking to build a IGBT controller, with CM600HA-24 modules in parallel, and use the Powerex driver. Seems like this driver board will do it, but has it actually been confirmed to work yet?
Why not use a BG2A board, already created with the parts?
