An apology with benefits, I hope...
Background
As I mentioned, I am wanting to tie my PSUs, because I need more wattage to test my DC Constant Current Load. I posted about the load project about one year ago.
At that time, I researched about tying PSUs in parallel to acquire more wattage and posted that under a separate thread:
https://www.eevblog.com/forum/beginners/how-to-connect-two-psus-to-get-more-current/msg1967069/#msg1967069I only remembered the findings of that research very vaguely, which led to my questions in this thread. I totally forgot that I had made a complete thread about tying PSUs... Well, in parallel, that is... My questions here are about PSUs in series, but I think all of the solutions are the same as for parallel.
In my sleep, tonight, I remembered something of the first thread and searched for it in my posting list. I found it.
The Apology
I think that the answers in my first post apply to series connections, as well as parallel... Meaning that I may have wasted your time on this thread. I own that.
I apologize for wasting your efforts and creating confusion. I am sorry. Please forgive me.
The Benefits
Several folks have said that an unbalanced condition in tied PSUs can not exist. The referenced post explains how it happens and offers practical solutions. The video at Post #6 does a good job of showing what is going on and how to solve it. So, perhaps for the folks that did not know that an unbalanced condition can happen, there might be the benefit of learning about it.
There is also the benefit of understanding that the diode solutions proposed here only address protecting against reverse power, not balancing. Maybe there is the opportunity of learning there, too.
I hope these benefits do exist, because I feel so bad about creating a wild goose chase. Again, my sincere apologies.
I will go back through the original thread and try the solutions. I will post my findings and, if the proposed solutions do not work, I will ask more questions. Until then, thank you for all your help.
