To keep up with this rapidly developing story its
best to follow the posts on,
[EMAIL PROTECTED]
For example, this recent posts may answer some of you queries.
===========================================================
To explain the voltage, the duty cycle is .05 and
the charts are labeled average voltage and average current.
It also appears that JLN is multiplying avg(v)*avg(i) to
obtain average power. This is not correct for pulsed
power calculation. Peak power must be calculated first
and them multiplied by duty cycle. For even more
accuracy a wideband power meter should be used.
These average the instantaneous power readings.
Huge errors result at low duty cycle when average
V and I are used.

===========================================================
I must admit that I have always been leery of VxA since I
learnt about electric motors and power factors. ;^)
As for the temperature differences they are a lot high for
the recent tests than they were for the earlier tests which
seems to rule out the pump objection someone raised.
