I would like to know how to build a power limiting circuit.
The goal is to be able to combine two PSU's with the same voltage in parallel in order to increase the Power output.
From what I've tested, when I connect two 9V PSU with a Y cable (in parallel), one of PSU's take most of the load and the other is outputing less than half the total Power.
What I would like to assemble is a circuit that would either limit each PSU's power draw to 9W (1A @ 9V or 0,75 @ 12V) or, at least, balance the load on each one (to draw 15W, one gives 7,5W and the other 7,5W as well).
Do you have any idea on how I could acomplish that?
