Hello
At first, let me tell you that you are doing very good work.
Then I have a suggestion.
I am service techniques for the UPS devices. And in UPS are all IGBT closed with -15V. However, I would suggest one driver with 15V pulses and colsing voltage -15V. Here is one already built
FUJI ELECTRIC - VLA517-01R - SINGLE IGBT GATE DRIVER 4A PEAK
I found one in the Farnell for 11.6
