Hi, I hope that you don't mind, I could not find a thread on this project and had a few questions.
I am assuming that the bike uses a permanent magnet rotor rather than a variable field coil due to its output characteristics and fairly high voltage.
If I understand your voltage regulator correctly, the circuit works by pulsing the connection on / off using the SCR, and then comparing this average output to the reference voltage.
What I am wondering is if this circuit can be made slightly more efficient with the addition of an inductor? The reason I ask, is that in traditional buck circuits, a similar on / off pulsing is taking place, charging up an inductor, and then letting it discharge to the load. The effect of this is that the (higher voltage x current) going into the inductor is then roughly the same as (lower voltage x current) going out of the inductor. If this were possible on this circuit, then the excess voltage from the alternator could be converted to even more charging current than the existing design.
Would this concept work, or am I missing something?
Take care,
Harry

Possibly, but I am not working on New Designs anymore. Except for a few personal items.
