Hello,

I have two offline SMPS's.

Vin = 85-265VAC
Vout = 50V
P(out) = 200W
Power factor corrected
Inrush limited.

I want these two SMPS's to do load_sharing with each other....and supply the 200W together.
-But if one fails, the other should be able to take up the full 200W output power.

So

How do we consider the feedback loop?

If both power supplies are stable and are prooved to be stable using a gain/phase analyzer....

....then when they are made to share...will the combined power supplies in sharing mode be stable too ?
