ok ok - i`m just a beginner, very beginner, so be a slightly indulgent :-)
then one more time:

i understand ethings about energy - the more - the better, as for the ROC -
it`s understandable too - to avoid corona loses and to get a discharge only
after full energy transfer from primary to secondary.
but what`s the use of too high voltage across the secondary? we can decrease
it by picking up a larger toroid, it =had to be decreased= at high Ep, coz
as H:D can`t be increased infinitely. and we don`t want any flashovers - do
we? :-)
now instead of the "minimum bps" question i`m asking about minimum
(at practical viewpoint) Vout - does it exist?
but maybe it`s just as with bps - do we need some middle value?
or we have to increase geometrical sizes and aspire to the maximum voltage?
:-)

Your not coiling unless your blowing capacitors! Then when you get
things worked out to where the capacitors stop blowing, you start
blowing transformers. (c) Richard Quick 11-03-93 20:42
