There must be some clever solution for this problem but I am finding it even
difficult to ask in proper order. Please read it all an help me find a clever solution.
I have two DC/DC converter
One is
Boost Vin(3-12V) and Vout(15V)
other is
Buck Vin(20-24V) and Vout(15V)
Now I want to combine both of these voltage(15V)
to provide more current for my load.
Now, I noticed one thing that if the Vin of boost is
higher than 15V it gives Vout of 16 V...etc...not 15v
also if Vin is less than 3V vout is about 5-6 volts.
Now what would be the clever way to give only 15V on the output
so that I can combine with the output of both buck and boost.
The main problem is as you may have already noticed by now that
at times i could be mixing two different voltage to cause
disaster.
I have attached a block schematic for further understanding.
