/diy/ - Do It Yourself

Ah, in case it's important, there is a AC/DC converter with adjustable output voltage that already can handle a variable AC input voltage, but it's for one power source.

diodes

>>1370283
>for one power source
or more if each has its own bridge rectifier

If it has to be done with one converter then it seems the only option is to put a ratchet gear on each dynamo

>>1370307
yes, so I asume but it doesn't solve the problem of how to connect muliple power sources as it's input.

>>1370313
using gears would be a solution indeed however I wonder if someone already solved it by using electronic components.

>>1370313
M are the dynamos

DIODE

>>1370319
You could do this:
-dynamos are in series
(-have a bridge rectifier on each dynamo if they are supposed to rotate in any direction)
-have a relay/transistor connected parallel to each dynamo
-measure rotations of the dynamo
-open the relay if dynamo rotates

>>1370322
hmm, a relais circuit isn't what I'm looking for also, it's not usable for dynamos in that configuration if two or more are active at the same time.

>>1370281
dynamo is dc
>>1370324
is the electrical version of this >>1370313

dynamo puts out ac, you are fucked.

>>1370331
>dynamo is dc

hmm, I didn't know that. I think my choices are still AC, though. I'll have to look into that.

>>1370329
>dynamos are in series
I'd rather not, thanks.

>>1370334
If they have different outputs then they have to be in series faggot.

>>1370335
if you run electricity through it, it becomes a motor. so series doesn't make sense.

>>1370337
that's why there's the other stuff you stupid faggot

>>1370338
I don't think you proposal works. It gave me an idea though about something else.

these in series
here a meme schematic
>>1370342
I don't think you understand shit.

>>1370344
putting them in parallel, using rectifiers and using relais to make AC from those DC would make more sense and probably is actually a solution then, but it's not elegant at all.

>>1370347
if they have different output they won't work in parallel you dumb faggot, only the one with the highest output voltage will provide power and will block the others
google how diodes work

>>1370350
not if your mass point is variable

>>1370355
lol

>>1370316
It does, that's what the BRs are there for.

>>1370483
Literally the bridge rectifiers.

Think about how an alternator in a car works and then put the rectifier bridge on the battery. Now what happens?

Well i dunno who i meant
