What size diode?
I've got a pedal powered generator using an old PM DC motor from a
treadmill. To charge my deep cycle battery, I'll need a diode to prevent the motor from spinning me backwards. How do I calculate the size that I need? The battery is 12V, and I'll rarely produce more than 120W of power. Do I just call it a 10A diode? Larger is okay too, right? Thanks. |

If the diode has no heat dissipation then I would use the diode of the size 2X the load, otherwise 10a would work. (120W * 2) /12V = 20 amps. |
