I have two voltage sources and I would like to get equal V_out from both sources to allow for a parallel connection. Does anyone have a suggestion on how I can use the Average DC DC converter to achieve this?

Hello everyone,
I am working with two voltage sources that I would like to use to charge a supercapacitor. I would like to program both sources to produce equal Vout so that I can connect them both in parallel. I have used the Average DC DC converter to my model but I am unable to get the same Vout from both sources. Does anyone have an Idea of How can do that?

Trying to place power supplies in parallel with each will cause great unhappiness. At best you might tie the outputs together through diodes as shown below.

You are probably correct about the difference in the regulating voltages causing your problem. The regulator with the larger voltage will source all the power while the second regulator falls below a current in its operating range resulting in the convergence difficulties. I suggest that you hook an isolated load to each regulator that draws enough current to allow convergence of each regulator. A simple resistor upstream of each isolation diode would suffice. Good luck!
