Modest IGBT SE project
As I couldn't resist buying some Infineon IGBTs for the start price at ebay, I was wondering what to do with them.
IGBTs are neither designed for linear circuits, nor were attempts to use them this way very successfull.
Anyway, I decided that working as a follower in SE class A, isn't impossible for any amplifying device which can stand the dissipation.
This resulted in this circuit idea:
(Actual IGBTs will be SKW20N60, didn't have a model for them)
Input and output dressing as well as protection is missing.
Bootstrap was the easiest way to work around the large turn-on voltage of the IGBT.
