Ray,
I think you are correct about RMS-peak ratio. It also correlates with
Trace's inverter manuals from the late 80's on, that to get full DC output
from the charger you needed to maintain 164V peak under load. The inverter
used the peak of the waveform, so a small drop in peak V meant a large drop
in DC A.

I beleive the the ratio for a pure

wrong,
