I'm looking for a voltage regulator:

Input: 10-50 V AC (Power source: Current Coil from an engine)
output: 10 V DC   Max. 1A

So its from a generator? i.e an alternator?

No its from an motorcycle

You need a rectifier to adjust ac to dc a capacitor and a 7810 regulator

AC current ? In your motorcycle ? There is no AC/DC converter right behind your coil ?

You can use an LM317, who has an output range of 1.5 - 37 V, @ 1.5 A max. You just need two resistors to use it "as is", but you can add capas an diodes to smooth output ... search for datasheet on google !

I forgot : you must convert to DC before using LM317 with something like that (just the diodes ...) http://everycircuit.com/circuit/4988264443281408

Motorcycles run on dc power though, so where or why would they need the ac part?

Taz8du29 ...I agree with him.

With a linear regulator for the DC ? 50V in and 10V out at 1A => does mean transform 40Watt into heat

Hurz : why it will waste heat ? If out is 10V @ 1A (10W) input would be 50V @ 0.2A (10W too !), no ?

Alternators and magnetos produce a/c current.

Thanks for your help Taz8du29. The motorcycle is from 1982.

@Taz8dus29, no the current in serial circuit is in all components in chain the same. So its also 1A and not 0.2!! Hope this helps.

@hurz oh ok ! Ty :)

@rich11292000 alternators have an integrated ac/dc converter (diode bridge + regulator)
