Hi,
I have wind turbine with 4 miniature generators. I am using two generators in series to power and Arduino I want to be able to switch between two and four generators in series as power sources for the Arduino without loosing power. This is because at low speed it takes all four generators to keep things alive. But at high speed the voltage is too large for buck-bust converter to handle. I can employ a Zener diode as voltage regulator but then I would be loosing in the efficiency. The voltage of each generator is monitored by Arduino. Cannot use a battery. Any help is appreciated.
