Lets find renewable solutions to reduce energy cost
Hi, here is company that shows the interior of their MPPT controller. It looks like they a using multiple circuits connected in parallel for higher amp output.
additional reference material, some of the articles may apply
found down load for DIY ferrite core inductor calculations
found commercial MPPT with data
I am just posting so I can compare my test results with what is available.
Hi, working on perf_board ciruit layout. Configured 50 volts caps at input to form a 1000uf at 100 volts. Not sure how well it will work. Rotary switch varies duty cycle from 10% to 50%, using 5 k potentiometer so each fixed percent value has small variable adjustment. Hopefully testing in a few days.

I wonder if they could recommend a plastic surgeon. My nose needs a little modification. :-)
Circuit update: currently constructing test circuit. Updated test points and added Vin discharge push button, also included on/off circuit power switch. Comments welcome.
Hi, test circuit update. This is the circuit I will be using for testing to establish duty cycle verses RPM for maximum current output to better understand MPPT algorithm requirements. I am using a fixed frequency 555 timer to drive a one shot 555 timer that uses a rotary switch to very the duty cycle. This should resolve the problems encountered with the earlier test circuits by providing a stable frequency when varying the duty cycles. I will post results when available.
