How does MPPT work?

Daox · 11-03-16, 12:49 PM

How does an MPPT controller work? What I mean is, how does it figure out the maximum power point? Does it monitor voltage and amperage output from the generator and keep messing with the dc-dc input and output? Kinda curious if anyone understands the logic of these controllers.

I'm thinking about a project I have and would like to do something similar, but its more of a wind power project where I have an alternator so I can control the field strength to get a desired output. Obviously it'll have to compensate for different wind speeds, and maintain voltage high enough to charge the battery pack. I know traditional voltage regulators do this job, but I will be modifying things to work at higher voltages, so I'll either have to modify or recreate the voltage regulator.
