I've got a fairly odd LED setup whereby a vehicle's alternator is being used to generate the power (rectified to DC) required to run said LEDs, which will be used for it's headlights. I would like to use PWM to control the brightness of the LEDs and bypass that pesky LED voltage-to-brightness curve. However I'm not sure how to handle the inductive kickback when the inductor is the thing generating all my power!
edit I have included a rough diagram. There will be voltage control circuitry to regulate the alternator (3 inductors) to the 36V i need, and the part numbers & values are not what I plan to use at all. But you can see now where I intend to apply the PWM much more clearly. I apologize for my previous ambiguity.
Do i treat it like any other inductor circuit or are there special concerns that i don't know about?
