Hand crank generator battery charger circuit

  1. Sep 12, 2011 #1
    Hello,
    I want to use a DC permanent motor as a generator in order to use it to charge a battery. This generator will be rotated by hand. The speed is varying as it rotates by hand. I would like to know what is the circuit that I could use it to charge 12 V chargeable batter?
    Best wishes,

    You would do basically the same thing that is done with car alternator circuits. You would follow the generator output with a rectifier and regulator.
