Hi Jim,

In looking at your post again I think that I see one problem with this.
There is no "DC voltage drop across the series resistor" per say. The actual
voltage drop across that resistor is the AC voltage drop that you see or
nearly so as the conduction angle is so small. You have short DC pulses that
are measured as AC. There is no steady state DC value across the series
resistor.
If you are measuring it with a meter the meter will not give a true
indication. 

The DC charging current , voltage drop across the series resistor, is going
to be pretty much the same as the AC.

that across Ro.
