Dear Bart (Bart Anderson -?), Dear All,
Thank you for your reply.
Please check, if I really „got it“ 100% right:
PERCENT CP CHARGED:
only dependent on:
HV trafo input voltage (possible variac boost ..)
HV trafo sec. voltage (trafo ratio)
HV trafo sec. peak volt. (above x 1,4142)
All above results in CHARGING VOLTAGE
Good.
BREAKEDOWN VOLTAGE
( JavaTC term: Arc voltage - MG space and electrode geometry dependent)
There is more to the gap that will alter actual values. Barometric
pressure, material, heat, etc.. Those are unknown, so the basic space
and geometry are used. It will vary slightly from the calculated.
PERCENT CP CHARGED = BREAKDOWN VOLTAGE/CHARGING VOLTAGE
As higher the result, as better performance of TCsystem (more cap energ)?
And as trade off more stress to the caps (their voltage security margin)?
Good compromise-result range for sound design -? (50–75%? 65–90%? …?)
The higher result means the cap can charge faster. There are also
transformer characteristics that can alter the actual charging current
(like ferro resonance) which is not computed. It gives a rough guideline
of the basic charging scheme. I would say 65% to 100% to be the range to
shoot for to ensure no problems in the charging area.
Time factor (Time between breaks, or BPS) what is influence to all above?
Yes, it is. The bps is affected by the gap and the charging voltage
which is controlled by the charging current. If you see in Javatc the
bps going low, the cap size and the transformer is the cause.
Take care,
Bart
