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 ...

No one said all power supplies are stable.
I know the Parallex converter. I can accurately state it is 100% stable when all components are within spec.
I also stated power supplies that have 45 degrees of phase margin are inherently stable. Having worked many years in that field, and done countless stability analysis and testing, I have confidence in that statement.

As for saying "When paralleling 2 supplies that are not designed to be paralleled together, you are effectively injecting a dynamic disturbance into each supply's independent feedback control loop.", that's BS. Adequate phase and gain margin will reject any dynamic disturbance. Plain and simple. This is as basic as it gets in feedback theory.

I guess I am just confused...
