Hello guys.
I know the topic title might be a little bad, but I really didnt know what to call this thread. Please let me know if you have better suggestions
I own an old Puch Maxi moped, but the generator is a little funky, it outputs waaay too high voltage than what I would expect to see.
So I want to rectify it, as I need DC voltage in the end, and measure the voltage when drawing a specific current, to see what I have to work with. Like when I draw 1A or 2A or something else.
When I measure the voltage with no load, I get up to around 100VAC free wheeling. (But I figure this would fall quite a bit when I put a load on it.)
My initial thought was to make a constant current regulator with a load, and then see what the input voltage on the regulator would be, when I change the drawing current. But I am unsure how to do this, so it can handle potentially 140VDC (100VAC rectified).
How would I go about doing this?
Any suggestions would be great. And please let me know if I need to elaborate on some things
