If this was a tractor question I know the answer, but for some reason I am not convinced it works the same way on a car, it should do but just in case..........
On old tractors you have a generator to top the battery up (really old tractors), on modern cars you have an alternator. Main difference being a generator is basically a back to from motor knocking out DC, an alternator is different phases in sine wave. Alternator goes into a bridge rectifier and produces DC?
Now at 800 RPM you get ~14V and at 6000RPM you get ~14V, my assumption is the voltage regulation and rectifier is inside the alternator??? Or is the regulation external?
I am asking because I have a variable speed device I want to turn an alternator, its just to keep a battery topped up like it would on a car. But Do I need to build the regulation circuit and current limit or do alternator already have them?
I am converting a 5KW 3 phase wind turbine (QR5 type) to a measly 14V 2A trickle charger.
