Paralleling Power Supply Units Made Easy ???
I am considering paralleling a couple of 20a variable adjustable psu's for 40a charging. According to what I have read on the world wide inter-web, it can be done quite easily, provided the following ...

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.

The paper is dedicated to parallel power supply operations for sharing current, which discusses many of the issues I have talked about, and you tell me I'm wrong.
Why would we need an explanation of how to design parallel control circuits if all power supplies can be hooked together without worry?
LOL...
