Hi All,
	I have received a number of inquiries about primary circuit RMS
current and using MMCCalc for different types of capacitors.  I modified
MMCCalc to be able to easily input the parameters of any MMC cap (that's
been needed for a long time ;-)).  It also displays primary RMS current now.
It always calculated that but never displayed it :-[  The new version (2.2)
can be found at:

The RMS current is calculated using the formulas in MMCPower4.html.  The
equations for resistance of a single cap (Rcap) and power dissipated in a
single cap (Wo) can be used to find current by simply using Ohm's law.
P = I^2 x R  ==>  I = SQRT(P / R)
So the RMS current in a single cap (which is the same for a single string)
is:
Irms = SQRT (Wo / Rcap)
The Primary RMS current is simply that number multiplied by the number of
strings
Iprms = SQRT (Wo / Rcap) x Nstring
