          Hello everyone,

        I'm pasting here the thread we've discussed a few weeks ago concerning what kind of rectifiers you use for your installations.


           good reading

Hi to all of you!

One quick question:

What kind of rectifier do you use for your wind installations?
(please provide a link to the product if available)

We will appreciate it if you spend 2 minutes and provide us with this information.

Thanks
Kostas

Hello All,

The controllers that we are using on the small wind generator (1.4M) has a rectifier built into it. 

We use a three phase rectifier on the larger turbine (4.0M), so that may be useful. eBay:

Make sure they are installed where there is decent ventilation, of course. 

All my best,

Michael

Hiya,
I wrote this guide for rectifiers while working in the Philippines:
http://www.re-innovation.co.uk/web12/images/stories/redocuments/information/SIBAT/WT_Rectifier_Guide.pdf

It might be useful to someone - it might need updating though....

For 12V 1kW systems we used:
70MT160K’B’
http://ph.rs-online.com/web/p/bridge-rectifiers/3953935/

For 24V 1kW systems we used:
36MT40
http://ph.rs-online.com/web/p/bridge-rectifiers/3953238/

For 48V 1kW systems we used:
26MT60
http://ph.rs-online.com/web/p/bridge-rectifiers/3952897

This was not the cheapest - it was more about reliable and repeatable supply in that situation.

Hope that helps,

Matt

Hello kostas

We use 3 of these:

About 4 USD each., so 12 USD for a wind turbine.

Hi Kostas,

Guess I am the last one to reply :)

I used these ones http://www.galco.com/buy/Vishay/26MT160 [1] in my
last 2 installation at India. Its always difficult to find three phase
bridge rectifiers in higher current ratings therefore have to hook it up
in parallel.

I would be using these in my upcoming
site, http://www.ebay.com.au/itm/Aluminum-Heatsink-Base-5-Pins-3-Phase-Bridge-Rectifier-25A-1000V-/331211534559
[2]. It comes as spare parts for some big machines in one of the shops
here and cost about $10.

Hope it helps.

Kind regards from Kathmandu,

Hugh

hi

I find the group a bit confusing so I hope this is posted in the right way.  

I have a couple of comments on the suggestions thus far.  One is that small 3-phase rectifiers (35 amps in square pack) are very expensive compared with single-phase ones of the same size, and it makes more sense to me to buy 2 or 3 single phase ones and wire them up for 3-phase duty.  Second comment is that the rectifiers with integral heatsink (attached to it) seem to have very small heat sinks actually and I would worry they would overheat unless you use a fan.  I prefer to mount the rectifier on a larger heatsink normally.

cheers
Hugh
