Hi Jan

Yes, I downloaded that AN today; will try to "throw together" Figure 5 with 
IGBT's and
IEEE dynamic voltage equilization circuit, and see what happens (like "run 
for cover!!!

    ;^))))

Speed looks right (~100nS turn on and off), FET is rated to nearly 20A 
pulse.  Might even be able to use a Radio Shack type IRF510 / IRF511 
variant for driving to keep
cost down.

Thanks again
