MMC Calculator Program
Hi All,
I wrote up a little program that will do all those nasty MMC calculations.
It is at:
http://www.peakpeak-dot-com/~terryf/tesla/misc/MMCCALC1.ZIP
It is a version 1.0 in QBASIC but it basically does the job. A sample
output is:
---------------------------
MMC Calculator Ver. 1.0 2/15/2000 Terry Fritz
Firing voltage = 12100
Fo = 145000
Break rate = 120
Cap value = 5.6E-08
Strings Caps/String Total Value Temperature Cost
3 7 24.00 11.41 30.45 Some Risk
4 9 24.89 7.31 52.20 Safe
5 12 23.33 4.56 87.00 Very Safe
6 14 24.00 3.63 121.80 Very Safe
7 16 24.50 3.02 162.40 Very Safe
7 17 23.06 2.79 172.55 Very Safe
8 18 24.89 2.60 208.80 Very Safe
8 19 23.58 2.44 220.40 Very Safe
-----------------------
It can be easily modified, copied, stolen, etc. as you please...
It does not do voltage but if you stay under 2000 volts per cap your ok.
It is sort of geared to my Panasonic caps but if you change the heat
dissipation constant in line 1260, it should basically work for any. It is
based of the calculations at:

Most things are worst case but the numbers seem to work fine. Hopefully
this will make MMC design much easier especially for the critical
temperature rise aspect.
Comment suggestions welcome. I am no computer programmer but the basics of
how the program works should be easy to see.
Cheers,
Terry
BTW - Thanks for all the great interest in my latest batch of Panasonic
caps! Looks like I won't be stuck with $1400 worth of them for very long
;-)) Hope I don't need another thousand...
BBTW - Reinhard, I just drew a straight line for the dissipation function.
Seemed to be close enough...
