Hi,

I put most of this along with the new schematic and parts list here:

Hi,

Late report...

It was trivial to add the diode tonight so I did...

It fixed everything!!!!! :-))))))))))))))))))

The gate drive voltage now locks right in at about 27V just like it is supposed too (these are all like 25kB "little" files now ;-)):

After the first peak, the IGBT is locked in good and hard ;-))

It "stays" on just like it is suppose to too :-)) That timing is trivial to change...
