A
full wave rectifier would be four diodes arranged to convert a positive or negative polarity to a single polarity. It is most often used in DC (
direct current) power supplies to convert the AC (
alternating current) after it goes through a transformer to DC.
I was thinking of the output like this to attach the cell phone charger to:
I was thinking of using the full wave rectifier (IPM1), just the four diodes of this one:
However, this 2nd diagram would work better since a typical voltage from a car is 12.8 to 14.8 volts. Change the
zener diode (PL13Z) to a 12.5 volt zener. The 12.5 volts and 0.6 volts across the transistor would make the
emitter follower circuit producer a 13.1 volt output.
I snagged the diagrams from here:
12vdc power supply circuits
Now a permanent magnet DC motor can be used to generate your power and put it to the input of the power supply circuitry. It just need to be large enough to produce enough voltage and current to your cell phone charger off what ever propeller you use. You might actually be able to use two large 12 volt computer fans in series to generate enough power, if you can get enough wind, but I don't think it's enough.
From your questions, I'll bet this is a bit overwhelming. Quite a bit to learn. Good luck.
