Hi All,
My motorcycle (400cc), when revving, the voltage reaches around 80V+ DC - bursted batteries and my regulator literally put my motorcyle on fire My solution as to not worry about replacing the regulator and battery ($90+) is to ride at around 40 kmh - but then again, when from stop (at first gear) sometimes revs up the motorcycle, eventually i'll have to carry a fire extenguisher or replace batt or regulator every so often
Here's what i have done so far, bought two (2) 100v/60a KRPC3510 bridge rectifiers, since my alternator is 3phase, and there is no 3phase bridge rectifier locally available. That takes care of rectification.
For the voltage regulation part I have questions :
1. What would be the best regulator circuit that can handle 90v (or more) max continuous input voltage
2. Since the primary function of the regulator is to charge the battery, does it need to be at more than 3A rating - when the motorcycle is running and all loads are on like lighting etc, will it draw more Amp from the regulator?
Most of the circuits i have stumbled upon are from AC to DC high Amp circuits, voltage regulators but with less Amp rating ... i found one widerange regulator 100v attached, but local parts availability is a problem ...
I have also looked at mechanical regulator of cars, but ... i wish i could understand more about it
Thanks in advance and best regards.
