I'm not sure what you want in the way of more details. Bridge rectifier
directly on-line with about 0.5 ohm series to represent the supply
impedance (otherwise you get infinite inrush current). Reservoir
capacitor say 470 uF and a resistive load that takes 30 W or so. Of
course, the SMPS switch doesn't look like a resistor, but at a fixed
input voltage it doesn't matter.
I don't know how good EWB is at this game; many people don't like it. I
use LTSpice, which was designed for the job, when Kevin isn't
looking.(;-)
I just did a quick simulation using EWB. I'm blowed if I can tweak
anything much away from a 2.5ms conduction period.
I had a small resistance in series with the supply that I varied from
0R1 to 5R. Still didn't change much though.
Do you recall any more details ?
