Looking at a previous post (#104)..is the "purple line" input current? From the link it appears so. If so...sorry, UGH! I haven't made a power supply that way since the late 90's. Is there a reason they aren't doing PFC with a a twinge of feed forward compensation? Maybe i'm off, but all my designs 100kW+ for power conversion. I just wouldn't do this. Even for my 100W supplies...I don't do this any more. I just got tired of the dealing with constant battle of inductor/capacitor balancing. I will say one thing about passive rectifiers....they are fast at transients which allows you to cheap out on the C. However, it sure jacks the hell out of the voltages in your house and what is present to your equipment.
