To Marco Denicolai & all:

Re Marco's IGBT-driver misfortune, I might have had the same problem:  I
was using some IR 2110 high/low-side drivers in a prior manifestation of
my FET t.c.  I found that they got zapped repeatedly, and so I finally
went to a transistor H-bridge driver of my own design.  I think the cause
was, that the 2110 and such-like incorporate a high-Z charge pump to
drive the "top" transistor.  The electric field of my t.c. was getting
into the IC and messing up that charge pump.  ...At least, that's my
theory.
