Paralleling Power Supply Units Made Easy ???

Now that's funny! Exactly what issues have you talked about?

That article talks about current sharing in voltage mode. The application we've been discussing is current sharing in boost mode. In boost, the PS is in constant current mode. There is not problem sharing current. There are no stability issues.

As the article states, supplies do not share current in voltage mode. You need extra electronics to force them to share. None of the supplies we've been discussing have this sharing capability. In our application, the supply with the higher voltage will supply all the current. All this has been discussed many pages ago. You're just hell-bent on arguing. I like it better when I had you on ignore.

Sigh...

Constant current paralleled is fairly easy for load sharing and straight forward.

Constant voltage is not, since the feedback loops may cause instability (oscillations) in the output voltage between the two supplies and load - even when Schottky diodes are used in series between the supply and load...

We are talking about power supplies in general.

You are the one now trying to cherry pick one possible condition for a converter/controller configuration which I did not...

EDIT: I'm done, you didn't comprehend anything I posted so I'm wasting my data bits...
