If I understand correctly, MPPC is a method of regulating solar panel
array voltage so as to maintain a constant array voltage over varying
loading. The voltage would be chosen to be about the MPPT voltage,
which varies little with current, more with temperature. It works because
the array efficiency varies little when close to the actual MPPT voltage.
The method I see proposed is to take a switching reg and reconnect
or swamp out the original feedback, from the output voltage, to the
input voltage. The use of temp compensation will be difficult if the
array is not close to the switching reg circuitry.
I have considered this approach, but not constructed any. Bruce Roe
