Re: Gap turn off at zero current and TVI



Hi Terry, Richie,
                  Interesting observations! You ask:

Try something I;'ve been meaning to try but never got around to: a 
snubber across the gap. Who knows - perfect quench might be just 
around the corner. So might a host of other interesting effects.
