Hi all

In case of several wind generator placed in the same area , how their output are electrically combined ?

For example 3 wing generators placed in the same field , how their electrical output are combined into one
single voltage so it will be used to drive the battery charger .

One way I thought is to rectify  each generator output and use blocking diodes
to feed the charger in parallel .

But I am not sure , it's just an assumption ..

Thanks

If its a big installation there are specialized inverter/controllers that will do power-point tracking to get maximum power from each into the main bus.  For a smaller setup you might try something simpler like paralleling the outputs - rather assumes the generators are identical in identical atmospheric environments.  The engineering involved depends on a lot of factors.

Sounds like you are thinking of several small wind generators for battery charging. If they supply DC the most you should have to do is put a large enough diode in each supply line so they can't back feed. This may not be necessary, depending on the design of the generators.
