How to connect two generators?

Question

Batteries

Good afternoon! The question is the following. It is necessary to connect two generators in parallel. When is it better to parallel them: after the rectifiers (one diode bridge for each generator), or use one diode bridge and connect the generators before it? I know that in parallel connection the current increases, but this applies to DC voltage. How will alternating current behave? Thanks for the advice!

Answer 1

when will you learn to write technically competently and in detail. all telepaths have long been on REN-TV.
what is the purpose of the merger?
what do you want to get as an output?
does the alternator produce bipolar or unipolar voltage??
other generator parameters, voltage, frequency ??
what is the diode bridge supposed to be used for??
With a parallel connection of DC sources with different voltages, it is possible that there will be a large current and failure of the sources. it all depends what and how to do it.

Answer 2

Connect after the diode bridges. (since for alternating current, phase matching is also needed)
It is understood that the generators are the same, but weak - therefore two are needed.

Answer 3

Thanks everyone for the replies. I need it for the following: I have a Shimano Nexave Di2 FH-C810 dual hub dynamo bike (front and rear). They are 3 watts, 6 volts. I want to get the output (using lm2596) 5 volts, 1 ampere.
