Perhaps this has been asked before,
But I have been thinking that the typical shunt method of voltage regulation and attendant heat issues might be better addressed by a switch mode voltage regulator.
I have scoured the net without finding much, and not really sure why.
If the typical motorcycle alternator uses permanent magnets flying past a coil to generate voltage, and that voltage increases with rpm, it seems to me that rectifying the voltage, dumping into a big cap, then using a switch mode power supply to supply 13.8V to the battery would be a much more efficient way of doing this task.
Any guru's have any insight into this?
I know that it's tough to get a voltage regulator rated for more than about 75V, and I'm thinking that 100V+ could be possible to see. Maybe a two step reduction?
