Nice job as always!

Could you do the kindness of posting the values of the resistors and diode.
I think that you did that earlier in the thread, but this is a pretty complete
picture of using the Revolt with a different power section.

Also, remind us of the part number of the IGBT module.
Is this pair "matched" for Vce from a case lot?
IE, it isn't two random modules put together.
I can see that you have used a number of poly caps here as well, and
that is a good thing!

Anyone contemplating this type of build will be well guided by this fine example.

Thank You for sharing!
